User Reviews

  • Totally free, works on even EXE archives, no nagging, works through Wine on Linux like a dream, installs quickly, just an all around awesome unzipper. Thanks!
  • The user interface is clean and minimalistic — not bloated at all. 7-Zip works excellently, and the 7z format is arguably the best available. However, I’ve been requesting a simple, user-friendly way to completely disable the folder history feature for a long time. Currently, the only method is by manually editing the registry, which isn't ideal. Implementing this feature wouldn't be difficult, but the developer has consistently ignored these requests. As a result, I would rate the support as poor.

  • Love it
  • 7-Zip offers excellent compression with the LZMA algorithm, supports multiple formats, and is user-friendly. It's lightweight, fast, and free. Perfect for managing large files and saving space. Highly recommended for anyone needing efficient file compression.
  • I would like to add compliments for a feature I have not seen described elsewhere: very fast copying of uncompressed files from one drive/folder to another. I have been frustrated by very slow copying of even small files by Windows File Explorer. Some other programs I have tried aren't a big improvement; maybe they are using Windows copying code. But 7-Zip does a great job, so thank you! (I use it in the "2 panels" view mode.)
