Karuzip started as a small archive tool that stayed out of the way. Every release since has been an attempt to remove one more thing that made people stop and think. This page is the honest version of that list: what already works, and what is being built now.
The further down you read, the less is settled. The line thins out for that reason.
Handling file types beyond extract and compress.
This one has no shape yet. Writing an undecided thing as though it were decided is exactly what this page is trying to avoid, so it stays at one line. When it firms up, it gets written here.
Everything above is the plan as it stands today. Order changes while things get built, and some of it gets dropped. We do not attach dates because we would rather not make a promise we cannot keep. Whatever becomes ready shows up in the GitHub release notes.
What changed in each release, starting with the first public version.
When Windows has marked an archive as downloaded from the internet, every file extracted from it gets the same mark, as the built-in Windows ZIP extraction does. File modification times stay as recorded in the archive. If the destination, such as a FAT32 or exFAT drive, cannot store the mark, extraction still completes and shows a warning.
Password-protected ZIP files are now created with AES-256 instead of ZipCrypto. The built-in Windows extractor may not open them, so the compression dialog shows a note above the password field.
When a name in the archive matches an 8.3 short name of a different existing item, Karuzip no longer overwrites that item. It saves the file under another name or inside the folder that the name points to. We also fixed archives in older formats such as ARC, SIT, and ZOO that sometimes could not be listed when file names contained Japanese or other non-ASCII characters, and extraction into an existing folder failing when the destination path is long.
The main window, right-click operation window, and file icons for 12 formats including ZIP, 7z, and RAR now share one design. Password visibility, sorting, log expansion, and maximize or restore icons follow their actual states. The icons support dark themes and reduced motion. The Karuzip logo stays the same.
Tab navigation now stays inside password and compression dialogs. ZIP explains why solid compression is unavailable and keeps your setting when you return to 7z. Switching the display language also updates the current operation result and action errors immediately.
Archive tests now preserve warnings instead of treating them as a clean result. Quitting during automation stops new work and waits for running tasks to stop. If they cannot stop in time, Karuzip stays open and explains why.
The direct installer has the same contents as 2.2.4, with no added features. It retains the fixes for English error messages, CLI arguments, and the final check before files are written.
Archive-test failures now use English in the English UI. The CLI accepts --password-stdin before or after the action name, and the final check before files are written uses fewer file handles.
Browse folders inside an archive and extract the selected contents. Completion now waits for final cleanup and checks. This release also improves compression presets, TAR.GZ / TGZ extraction, default-app checks, garbled-filename guidance, and CP949 support.
Compression settings now explain that ZIP encryption leaves filenames visible. If names also need to be hidden, the same screen points you to 7z.
Archives arriving in a watched folder now start processing correctly, and corrupted archives can be moved to quarantine. The fixes cover local Windows paths and UNC network-share paths.
The new automated processing feature ships three templates — inspect and extract incoming archives, batch health-check a folder of archives, and compress with a final verify — and runs only while Karuzip is open. This release also adds a pre-extraction check (encryption, item count, unpacked size), a searchable processing log, and a manual-only diagnostic export.
Extract here, Extract to folder, and View contents now sit right in the menu, and extracting into an existing folder no longer silently half-overwrites it on failure. The official installer now bundles the karuzip-cli command-line tool.
The interface, the right-click menu, and the file type names all follow the app language setting. Failure messages started distinguishing between low disk space, denied access, and a damaged archive.
Extract, integrity check, and compress show their progress without opening the main window. Compressing straight to ZIP or 7z from the right-click menu was added at the same time.
Of those, 230 have sample or automated verification and 12 also have evidence from a real Windows machine. This release also added split archives (extract and create), a manual filename encoding switch for older ZIP files, an archive integrity check, and search and sort inside an archive.
Rebuilt to follow the Windows 11 right-click menu conventions rather than bolting onto the legacy menu.
On some machines the Karuzip entries never appeared at all.
New versions are announced at startup and can be installed from there.
Drag and drop, extract and compress from the right-click menu, password-protected archives - and the original promise: no ads, no bundled software, no data collection.
The full change-by-change record lives in the GitHub release notes.
