SoftwareApp	1220aa6679	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.	2026-10-17 02:06:19 +02:00

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.

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.

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.

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.

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 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.
