What is B1 file?

A file with a B1 extension is associated with a B1 Compressed Archive, developed by Catalina Group. This file type belongs to the Compressed Files category and is saved as a Binary file.

A B1 file is a compressed archive created by B1 Free Archiver, a proprietary freeware multi-platform file archiver and file manager. These files are compressed using Lempel-Ziv-Markov chain Algorithm compression. Such files may also have a password for additional protection. B1 files commonly contain several files or folders compressed and combined into one single file.
