What shipped, and what we are building

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.

What we are building

The further down you read, the less is settled. The line thins out for that reason.

Karuzip 2.0 Being built now

Rebuilding what happens when an extraction goes wrong.

Extracting an archive is the easy part, and it already works. What 2.0 rebuilds is everything after that: making sure a failure never takes your existing files down with it, and making sure you can tell why it failed without guessing. Unglamorous, and the part we were least comfortable with.

  • Extracting into a folder that already has files will not damage what is there Today, an overwrite that stops halfway can leave a half-written file behind. In 2.0 the extraction is assembled somewhere else first and applied in one step at the end. Cancel it midway and your existing files are untouched. The trade-off: it temporarily needs roughly as much free space as the extracted result.
  • Archives on network shares and NAS devices will open On some NAS setups, extracting an archive stored there simply did not work, and nothing was written to the log either, so the cause stayed invisible for a long time. We found it, and it is being fixed.
  • A failure will say what actually went wrong Instead of ending at an internal error, Karuzip will distinguish between running out of disk space, being denied access, and a damaged archive - and where there is something you can do about it, say what.
  • A command you can call from your own scripts A small command-line companion ships alongside the app, so a batch file or a script of your own can drive Karuzip. Irrelevant to everyday extraction, and a real difference if you do the same job every day.
Karuzip 2.1 After that

Letting Karuzip take over the repetitive part.

Files land in a known folder, and get dealt with the same way every time. We want to take that loop off your hands. The machinery for it already sits on the 2.0 foundation; what remains is making it something you can set up from the screen rather than a config file.

Karuzip 2.2 Further out

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 shipped

A little over a year since the first release. Only the changes that mattered.

  • 1.4.5August 11, 2026The app in English. 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.
  • 1.4.0August 1, 2026A small window just for right-click jobs. 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.
  • 1.3.0July 28, 2026320 registered extraction extensions. 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.
  • 1.1.0July 19, 2026The Microsoft Store edition. Rebuilt to follow the Windows 11 right-click menu conventions rather than bolting onto the legacy menu.
  • 1.0.3July 2, 2026Fixed the missing right-click menu. On some machines the Karuzip entries never appeared at all.
  • 1.0.2July 1, 2026Automatic updates. New versions are announced at startup and can be installed from there.
  • 1.0.0July 1, 2026The first release. 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.
