Free WinRAR and WinZIP Alternative – B1 Archiver

B1 Free Archiver is a great alternative to WinRAR and WinZIP utilities. It has a clean and simple interface that allows you to browse and manage your archiving tasks easily. B1 supports .rar , .zip and b1 formats, but more will be added soon. If you have used other software for archiving until now, B1 will successfully replace it. Files and folders can be compressed and saved into a single .rar / .zip archive that is fully accessible from another computer using a different file archiving utility.

If you already have created an archive, B1 may turn helpful as it is so easy to use the shell context menu to add more data to that specific archive without the need to create yet another one. Files that are opened and modified from within the archive are saved automatically through the archive updating feature.

Files can be extracted from within the integrated shell menu in the same folder as the archive or in any other folder you choose. B1 archiver was developed along with an improved compression algorithm. That leads to faster and better compression ratios in comparison with previous software applications. It can turn useful when the computer runs low on space and/ or you need a simple operation done fast.

We should keep an eye on the developers of this application because it seems that they will introduce the possibility to encrypt files in an archive with the 256 bits algorithm in the near future.

B1 is an open source project. The developers’ community actively contributes to its constant improvement. This gives B1 the upper hand on other similar apps that may not be so frequently updated.
