Rename a whole batch at once, numbered on from the folder's own series
Selecting more than one file and choosing Rename now opens a pattern dialog rather than the
single-file one: a name, the number to start at, and a live preview of the names it will produce.
The number is the part that makes the feature worth having. A batch rename that always starts at 1
is useless the second time it is used, because the first batch already owns 1 to 12, so the dialog
reads the names already in the folder and starts at the highest "base (n)" it finds: a folder
holding "series (1)" and "series (2)" makes the next batch start at 3, which is the market survey's
most-helpful complaint answered exactly ("if I later find another group of photos which I want to
continue the batch naming with 'Ice (3)...'"). Three rules in core/BatchRename are decisions rather
than defaults, and are written down as such: the extension is kept per file, so a mixed batch of
.jpg and .png keeps each file's own; the series is counted across extensions, because "Holiday
(9).png" making the next number 10 is one series while "Holiday (10).jpg" beside "Holiday (1).png"
is two; and it continues from the highest number rather than from the first gap, because someone
renaming a second batch is carrying a series on rather than filling in the holes of one, with the
start number theirs to type where a gap matters more.
The batch is planned in full before a single file moves, and the plan has three answers and
deliberately no fourth: Ready, Blocked (naming the target that is already in the folder) or
NothingToDo. A batch that renamed nine files of twelve and then stopped would leave the user to work
out which nine and to guess whether the last three crashed or were skipped, so a collision refuses
the whole batch, the dialog names the file in the way and disables its button as the name is typed,
and a chain is declined outright - "a.txt" taking "a (1).txt" while "a (1).txt" is itself in the
batch would need the files shuffled through temporary names. Every rename still goes through the
same FileOperations.rename a single rename uses, so the refusal to overwrite anything is the same
one, and the successful renames are collected into the single Undo.Relocate step that already
existed: a feature that touches twelve files at once owes the user one tap back. The action bar now
offers Rename to any selection, since which of the two dialogs a tap means is described by the
dialog that opens rather than by the bar; Details stays single, because "the details" of twelve
files is not a screen.
Writing it turned up a quieter bug in the rename that was already there. rename(path,
"notes/final.txt") built a child path, which resolves into the subfolder rather than alongside the
file, so a name containing a separator moved the file instead of renaming it and nothing in the
dialog or the listing showed that anything had happened. Both rename paths now refuse a name that is
not one path segment (core/FileNames.isUsableName), and the dialog says which rule it is while it is
typed, which is where the user can still do something about it.
Twenty new core tests (BatchRenameTest, FileNamesTest) and six through the view model, 350 JVM
tests in total, lint clean. Verified by driving it on the phone against a folder that already held
"series (1).txt" and "series (2).txt": with three files selected and "series" typed in, Start at
moved to 3 on its own and the preview listed "series (3).txt, series (4).txt, series (5).txt";
afterwards the folder held all five series files, each file's contents having travelled with its
rename and the two originals untouched, and the snackbar's Undo put a later batch of three back in
one step. The collision and the slash were driven the same way - the file in the way named with the
button disabled, and "A name cannot contain a slash" - and the scratch folder was removed from the
device afterwards. CHANGELOG, ROADMAP (M14), COMPETITIVE_ANALYSIS (the gap moves from candidate to
closed), STORE_LISTING and EDGE_CASE_TESTING carry the feature, its decisions and the pass itself;
two tooling notes went into the last of them, that "adb input text" does not deliver a slash and
that the dialog lifts once the keyboard appears.

Put running the release build on a device into the checklist, and re-measure it
The R8 defect fixed in the previous change was invisible to every check that existed: it passed the whole unit suite, passed lint, and worked in the debug APK, and the release APK was the only thing that disagreed. Nothing in the process had ever run it. The checklist now has a section for that, placed with the artefact work rather than at the end, because the order in which the document is meant to be worked is build, run it, then declare things to Google. It carries the install commands (the release build is a separate package, so it can sit beside the debug one and be compared directly), the MIUI trap that a bare INSTALL_FAILED_USER_RESTRICTED means its dialog was answered late rather than that the APK is bad, the paths most worth walking (thumbnails, an operation long enough to show the notification, the two SQLite databases, each viewer, the FileProvider), a dumpsys check of what the installed build actually holds rather than what the APK declares, and the one instruction that matters when something differs - assume R8 removed something instead of assuming the feature is broken, because a class named only from a resource or reached only by reflection looks unused to a shrinker. A last item points the walk at the demo library from the screenshot section, so it is repeatable and a reviewer's own files stay out of it. Renumbering meant fixing four references: two inside the checklist, and one each in STORE_LISTING (the screenshot section is now 7) and MONETISATION (pricing is now 8). A checklist that points at the wrong step is worse than one that points nowhere, so they were traced rather than assumed. Section 3 also gets a fresh measurement, since its own rule is that a stale hash is worse than no hash because it reads as though it had been checked. The record it replaces was from 2026-10-15 and predated the library views, the duplicate finder and video thumbnails: the AAB is now 5 181 628 bytes (sha256 f053d90f...) and the APK 2 294 021 bytes (sha256 afe03dea...), both versionCode 1 / versionName 1.0.0 / targetSdk 36, with the permission set unchanged and still without INTERNET or any READ_MEDIA_*. Two smaller repairs came out of the same pass. A link added in the previous commit pointed at EDGE_CASE_TESTING.md from the repository root, where it does not resolve - the changelog's other links all carry the docs/ prefix - and that was found by writing a link checker and running it over every relative link in the markdown: 37 of them, none now broken. And the re-measure warning had ended up stated twice, once per measurement record, so it now appears once, after the newest numbers and immediately before the upload steps. Documentation only; no code changed, so the suite stands at 324 JVM tests and lint clean. The walk itself was done on the phone in the previous change - what is new is that the process now asks for it, which is the part that would have caught the defect in the first place. |

Give a video row a frame of the video, and fix what R8 was hiding
A video row showed a film-strip icon, and a phone holds more video than anything else, so a column of identical icons said nothing about which clip was which. Images and videos now take the same path - EntryIcon hands Coil the file, and for a video the request asks for a frame - which cost exactly one dependency: io.coil-kt.coil3:coil-video, at the same version as the Coil already in use, whose own POM adds nothing that Coil did not already bring (coil-core, kotlin-stdlib, core-ktx). No ExoPlayer, no media3, and no new permission: the decoder is the platform's own MediaMetadataRetriever. Two details are decisions rather than defaults. The frame is taken one second in, because the first frame of a recording is very often black or the middle of a fade-in, and a thumbnail of a black rectangle is no more useful than the icon it replaced. And a decode that fails - an unsupported codec, or a file only pretending to be a video - settles on the icon rather than leaving an empty square, which the row remembers so it is not retried on every recomposition. The dependency also nearly shipped a feature that did not work. coil-video registers its decoder through a META-INF/services entry, and in a debug APK that is enough: the file and the class it names are both there, and frames decoded. In the release APK, R8 removes both, because a class mentioned only from a resource looks unused to it. So the feature worked in every build that had been looked at and would have failed silently in the one users install - the worst shape a bug can have, since it needs no code change to "fix" and would have been reported as "video thumbnails don't work" against a build nobody had run. The factory is now registered explicitly against an ImageLoader in FileManagerApplication, which makes it a code reference R8 cannot drop, and the release APK was installed and driven to the Videos library to confirm the frames decode there too. That also closes the gap noted two changes ago, that no ImageLoader was registered at all; its cache sizes are left to Coil deliberately, since they are derived from the device's heap and a number written here would only be a guess. The same run found a smaller thing that no test could have: opening the search field from inside a library left the scope on "this folder" - the hint read "Search this folder" and a folder toggle sat beside it - while the search in fact ran everywhere, because the view model has always known that a library is not a folder and answered from the index instead. The behaviour was right and the screen was wrong, which is the same shape as the volume-list bug fixed earlier and the same root cause: the switch-on-open asked whether this was the root list rather than whether a folder was open. It now asks for a path, and the scope toggle appears only when there is a folder to choose about, because its two settings did the same thing otherwise. Every other use of isRootView was then checked for the same conflation and none was found. One test was added for the search behaviour; the scope mismatch itself is not testable, being a disagreement between two correct pieces. 324 JVM tests, lint clean. Verified on the phone in both builds: two clips made with ffmpeg (a testsrc2 pattern and SMPTE bars) drew their own patterns as thumbnails, beside a real 4.3 MB video from the device's own storage, and the demo library's three zero-filled stand-in .mp4s fell back to the icon - which exercised the failure path with material that happened to be lying around. The release APK is 2 294 021 bytes and still declares no INTERNET. Not done: the store screenshots still show the home screen from before the library views, and the release build running on a device is in nobody's checklist - which is exactly why the R8 problem survived until now, and is the first thing worth adding. |

Browse the device by what a file is, and find the ones that hold the same bytes
The root screen opened on a list of volumes, so "where are my photos?" began with knowing which folder they were in. It now opens on Libraries - Images, Videos, Audio, Documents, Archives and Recent - each row saying how many files the index knows of that kind, and each opening an ordinary listing with thumbnails, sorting, multi-select, details and the existing viewers, so a tap on a photo opens the image viewer and a tap on a PDF the PDF viewer. Downloads and New files are deliberately absent: one is a folder shortcut and the other a time window, and presenting three different things as one feature is how a listing starts lying about itself. Documents includes .txt, because a user looking for their documents means those too, and DIRECTORY, APK and OTHER belong to no library at all - a test asserts the three omissions so they stay decisions rather than oversights. A library has to ask for "every image" without reading a name, so IndexedFile gained a derived kind beside FileEntry's and the index stores a copy of it to filter on: schema v3, with a migration that rebuilds the files table and deletes the volume stamps with it, because a stamp means "the rows behind this are this current" and a rebuilt table has no rows behind it. Rebuilding rather than backfilling is legitimate only because this index is a cache of a walk that can be repeated; SqliteTrashIndex's rule is the opposite and its own documentation says why. A library then obeys the indexed search's two rules exactly: the answer comes first with the walk behind it, and every row is confirmed against the filesystem before it is shown, with the rows whose file has gone forgotten rather than displayed. On a device that has never been indexed the first tap on Images therefore starts a walk - which the screen admits to, using the progress row the search already had, instead of showing an empty library that reads as an empty device. "Find duplicates" in the overflow compares contents in three passes, cheapest first: size, which the index already knows, so the candidate list is one query and reads nothing at all; the first 64 KB of every candidate, a filter whose only power is to rule files out; and the whole file for whatever survives, which is the pass that decides. The separation is enforced by a test that builds two files sharing their first 64 KB and differing afterwards and asserts both were read in full - it would fail if the cheap pass were ever treated as an answer. The screen shows only what was measured: groups ordered by the space deleting the spare copies would give back, each header stating the copies and what they cost, every row carrying its folder as well as its size, and nothing preselected, because which copy to keep is the one decision the screen exists to hand over. A file whose bytes cannot be read is counted and reported rather than skipped, "nothing found" is never claimed without saying how many files were compared, and deleting closes the scan instead of patching it - its rows came from comparing bytes, and quietly dropping some of them would leave a list that still looks like a scan while its headers claim numbers nobody measured. The thumbnails went from 28 to 48 dp in a list row and 40 to 96 dp in a grid cell, with the grid's minimum column width raised to 144 dp to suit them; ListItem measures its leading slot rather than capping it, so a row grows to fit instead of clipping. That turned out to matter: the commonest complaint in the competitive survey is thumbnails that load only once scrolling stops, which is the failure mode a larger thumbnail invites. Two smaller corrections came out of the same work - a mutation now re-reads whatever is on screen, so a delete from inside a library removes the row instead of doing nothing at all because there was no path to reload, and returning to the app re-reads a library rather than dropping the user back to the roots. docs/COMPETITIVE_ANALYSIS.md records the market leader's features and what its users praise and complain about, with the sources that were blocked and the size of the review sample stated rather than glossed over; it is where both features came from, and the gaps that cost no permission are listed as candidates in the roadmap. 323 JVM tests (34 added across the two features), lint clean. Tested on the real phone - the same M2101K7AG, with the debug build installed past MIUI's two gates. The libraries on a cold index (no counts rather than a row of zeroes, "Indexing 300 files..." on the first tap, then "Index updated" and real thumbnails), the counts afterwards (Images 6238, Recent uncounted), a tap opening the viewer and BACK returning with the scroll position, and a duplicate scan that found four genuine groups in the device's own storage with nothing crashing. The duplicate delete was deliberately not pressed on a device that is not ours to empty, the store screenshots predate the new home screen, and the library views turn the M10 screenshot rule into a privacy question as well as a cosmetic one - all of that is recorded in docs/EDGE_CASE_TESTING.md rather than left implicit. |

Preview files inside an archive, and search every volume from an index
The archive preview could say what a zip held but not show any of it, and the search could only answer "is it here?" for the folder tree the user was standing in. Both are now answered. ArchiveEngine gains a single-entry reader: a ZIP the backend can seek jumps straight at the entry's data through the central directory, 7z scans its index, a streaming container decompresses past whatever is in front of the entry, and a compression wrapper has exactly one entry whose name is derived from the archive's own. extractEntry is rewritten on top of it, so there is one implementation of "reach this entry" rather than two that could disagree, and the now-dead extractFromZip and only= parameters are removed. A tap on a row now previews and the row's action extracts, which is what a row means everywhere else in this app. Text and markup are read into memory, so the commonest question - what does this readme say - writes nothing at all and works in both storage modes. Everything else needs a file a decoder can open, so the entry is copied into the app's own cache, one folder per preview and under its own name so the viewer's title bar does not read copy-0.png, and deleted when the preview closes with a non-recursive delete. The copy is a real path, so image, PDF and media previews work even in the SAF fallback, where the browsed files cannot be previewed at all. A copy has no file to save back to, so the text editor shows no Save and markup offers no editor; closing returns to the archive rather than out of it. SearchIndex is a small port over SQLite beside the trash index, inheriting that one's doctrine that an index is not the truth: a reader drops rows whose file has gone and forgets them, freshness is reported rather than assumed, and a volume's rows are replaced wholesale so an interrupted pass leaves the previous listing rather than half of this one. Timestamps are written only when a pass finishes, so a walk cut short by a new keystroke reads as older than it is, which is the safe direction to be wrong in. Names are matched with NameMatcher's semantics translated into LIKE - substring, anchored glob, and a literal % or _ escaped - because a search that quietly widens what was typed is what an index does badly. The search field gains a scope toggle, and every search everywhere carries the age of the index and a way to rebuild it, because a search that silently omits what arrived since the last walk is worse than one that spends a minute being sure. Rows are written in batches of 500 and the counter reported every 100, since a row reading "0 files" for the whole first second reads as nothing happening. Deliberately not a foreground service: a pass runs while the screen is up and stops when it is not. Verified on the API 35 phone rather than inferred: a .txt and a .png inside a real zip, both previewed from the archive list with their own names, the copy gone on close and the archive list restored behind it; then the first search building the index with a full walk, and a search after an app restart answering instantly and finding a file in Download/cline-zip while browsing Internal storage. Watching it caught two lies, both fixed here: the empty state claimed "Nothing matches" while the index was still being written, and two progress bars stacked on each other. 268 JVM tests, lint clean, release APK builds and installs. The store listing gains the archive preview and the scoped search and is re-measured at 2730/4000. |

Unpack .tar.bz2 and .tar.xz, which only half-extracted
formatOf matched .tar.gz/.tgz as a combined format and then fell through to the bare .bz2 and .xz wrappers, so a .tar.bz2 was read as one compressed file: extracting it decompressed a single layer and left a .tar to extract again, while the same archive named .tar.gz unpacked in one step. The store listing advertised "extract ZIP, TAR, TAR.GZ, GZ, BZ2, XZ and 7z", which reads as though they all behave alike. Found by extracting one archive of every supported format through the UI on the API 35 AVD rather than trusting the suite. A real z4.tar.bz2 left z4/z4.tar - raw ustar headers and all - beside z3.tar.gz fully unpacked to z3/a.txt and z3/sub/b.txt. TAR_BZIP2 and TAR_XZ now sit alongside TAR_GZIP, detection consumes the whole tar suffix (.tar.bz2/.tbz2, .tar.xz/.txz) before the bare compressor, and the engine gains the two readArchive branches. The bare spellings still mean a single compressed file. The suite had a gap that let this hide: only ZIP, GZIP, XZ and 7z had round-trip tests, so neither plain TAR nor TAR_GZIP did, and there was nothing for the asymmetry to contradict. All four tar spellings have one now, built in memory with the same library that reads them. 212 JVM tests, lint clean. Also records the format sweep in EDGE_CASE_TESTING and re-measures the release artefacts (aab 4 838 235 / sha256 e1d23130..., apk 2 155 455 / sha256 37fb46cb...). The APK byte count happened to land on the same figure as the previous build, so the new literals were confirmed present in the shipped dex rather than trusted to the size. |

Receive shares and serve file requests, so other apps can reach this one
The manifest had nothing but a LAUNCHER filter, so no other app could hand Plain Files anything. It now registers for ACTION_SEND and SEND_MULTIPLE (a bar over the browser: navigate to the folder, then Save here) and for GET_CONTENT and OPEN_DOCUMENT, where tapping a file hands it back through the existing FileProvider. Both reuse the browser instead of a second screen, because both are navigate-to-a-folder with a different verb at the end. data/ gains one port, IncomingSource, to keep a ContentResolver out of the ViewModel the way DeleteRequestFactory keeps one out of the delete path. Shared files are named from the sender OpenableColumns, allocated by the same NameAllocator a paste uses, and deleted again if they cannot be read rather than left as zero-byte stubs. While providing, a tap on a file chooses it but a tap on a folder still navigates, or the user could never reach the file. ACTION_VIEW is deliberately not registered: the app already hands files out through the system chooser, and registering as a viewer would offer Plain Files back to itself. No new permissions - the merged release manifest still declares no INTERNET. |

Support 7z extraction, and fix .xz extraction which would have crashed at runtime
Commons Compress declares its LZMA/LZMA2 support against org.tukaani:xz as an *optional* dependency, so nothing pulled it in transitively and nothing failed at build time. The app nevertheless advertised .xz as extractable, so the first user to open one would have got NoClassDefFoundError: org/tukaani/xz/FilterOptions. XZCompressorInputStream references org/tukaani/xz/XZInputStream directly. The library is now declared, and a round-trip test covers the path that was silently missing. That same library is what 7z needs, and Commons Compress already ships a pure-Java 7z reader, so 7z extraction costs no native code and no further dependency. The docs had assumed the format was off limits and said so in three places, including the customer-facing store copy. 7z is the only format here that cannot arrive through a stream: its header sits at the end of the file, so the reader has to seek. That is now a capability the backend advertises, StorageSource.openSeekable: the all-files backend answers with a real FileChannel, the SAF fallback with null, so folder mode reports needs-a-seekable-file instead of failing obscurely. Entry names go through the same ArchivePath.safeRelativePath zip-slip guard. 7z creation stays deferred. |
