Is 7-Zip safe?
Yes, 7-Zip is completely safe when downloaded from the official website (7-zip.org) or the official GitHub releases page (github.com/ip7z/7zip). It is open source, meaning its code is publicly auditable. Always verify the SHA-256 hash of downloaded files and avoid third-party download sites that may bundle malware.
Is 7-Zip open source?

Can 7-Zip open RAR files?
Yes. 7-Zip can fully extract RAR and RAR5 archives, including multi-volume (split) RAR files and password-protected RAR files. However, 7-Zip cannot create RAR files due to the proprietary nature of the RAR format. For creating RAR files, you would need WinRAR.
Can 7-Zip create RAR files?
No. 7-Zip cannot create RAR files because the RAR format is proprietary. The unRAR license allows extraction but not creation. For most use cases, the 7z format provides equal or better compression and is completely free. If you specifically need RAR, use the official WinRAR software.
Can 7-Zip open ISO files?
Yes. 7-Zip can open and extract files from ISO disc images without needing to mount or burn them. This is useful for retrieving individual files from installation media or software distributions.
