Karuzip is a focused Windows archive app. The common questions are not whether it is free, but which Windows route to use, what formats it can honestly handle, and where its workflow intentionally stops.
Install
Which Windows versions does Karuzip support?
The Microsoft Store version is for Windows 11. The 64-bit direct-download installer supports Windows 10 and Windows 11.
Where should I download Karuzip from?
Official Karuzip downloads are limited to karuzip.com, GitHub Releases, and Microsoft Store. Treat third-party mirrors and repack sites as unverified.
Why can Windows show a SmartScreen warning for the installer?
The direct-download installer is an unsigned beta, so Microsoft Defender SmartScreen can show an unrecognized-app warning. That is a reputation warning, not proof of malware. If you want the least warning friction, use Microsoft Store on Windows 11.
Using it
How do I open an archive safely in Karuzip?
Open the archive, inspect the file list, and run Check integrity when the archive is uncertain before you extract into a destination you care about. The guide at How to use Karuzip walks through that workflow.
Can I look inside an archive without extracting it first?
Yes. Use View contents to inspect the file list, search, sort, and extract only selected items later. The dedicated guide is View archive contents without extracting.
Can I process more than one archive at once?
Yes. Karuzip can queue multiple tasks, but each task remains separate so you can retry or cancel one item without pretending the whole batch is one opaque job.
Formats
Can Karuzip open RAR files?
Yes. Karuzip can extract RAR archives, but RAR creation is not part of the product.
Can Karuzip create password-protected archives?
Yes. Karuzip can create password-protected ZIP and 7z archives. Passwords are used for the current operation and are not stored in settings or history.
Can Karuzip open split archives?
Yes, if you have the full set of volumes and start from the first part. The guide at Open split archive files on Windows explains the exact boundary.
What does “320 extensions” actually mean?
It means 320 registered extraction extensions routed to an archive engine. Karuzip separately states that 230 of those have sample or automated verification, 12 of those also have real Windows-machine evidence, and 90 remain engine-capable without a verified sample result.
Safety
Does Karuzip send telemetry from the app?
No. The app has no ads, tracking, or telemetry. The website uses analytics separately, after consent, and that boundary is described on the Privacy Policy page.
Can the app contact the network later?
The website-downloaded edition may contact GitHub Releases to check for updates. That does not include your archive contents, file names, or in-app usage telemetry.
Is the public GitHub repository the full source repository?
No. The public GitHub repository is the public release-file and notice surface. It is not the private product source repository.
License and project boundary
Why is Karuzip free?
Karuzip is positioned as the free front-door product in a wider tool line. The archive tool stays free, ad-free, and quiet while future paid products can carry later monetization.
Where are the third-party notices?
The public repository and release materials carry the notice surface for shipped dependencies. That includes the release-file context users need when they want to verify what was distributed.
Where should I ask for help?
Use support@karuzip.com for private support and GitHub Issues for public, reproducible problems.
Still stuck?
Start with the usage guide if the question is about a workflow, or contact support if you have a private archive problem that should not become a public issue.
