B1 Archiver

Fast versatile file compression and extraction tool

B1 Archiver is a powerful, no-nonsense utility designed for anyone who regularly works with compressed files. Its biggest strength is format support: beyond the usual ZIP and RAR, it handles B1 and more than 30 additional archive types, including 7z, CAB, ISO, TAR variants and many others. This makes it a reliable companion whether you’re dealing with simple downloads or complex backup sets.

The interface is clean and intuitive, blending a basic file manager with archiving tools. You can navigate folders, copy, paste, delete and rename files, then instantly compress them into ZIP or B1 archives. Creating password-protected archives is straightforward, and opening secured ZIP, RAR, 7z and B1 files works smoothly, making it a good option for handling sensitive documents.

B1 Archiver shines when working with large or complex archives. It supports multi-part RAR and B1 sets, and lets you browse the contents without extracting anything first. Partial extraction is another highlight: instead of unpacking a whole archive, you can choose just the files you need, saving both time and storage space.

Performance is generally quick and stable, with progress shown in the notification area while tasks run in the background. Useful touches such as favorite folders, multi-selection, and the option to hide files from media scans help it double as a lightweight file manager. Localization in more than 30 languages also makes it accessible to a wide audience.

The free version is supported by ads, which can feel intrusive during longer sessions, but upgrading to the Pro version removes them. Overall, B1 Archiver is a versatile and dependable compression tool that comfortably covers both everyday use and more demanding archiving tasks.
