Editors' Review


File compression and archiving software remains among the most popular downloads, even though Windows integrates a basic but capable compression utility. Aftermarket archive tools tend to be faster, more powerful, and more capable than the Windows utility, and you've got plenty of them to choose from, too -- many of them freeware. We've tried all the big names, including WinZip, 7-Zip, and WinRAR. One tool we haven't tried before is B1 Free Archiver, and we wish we had. This free file compression and archiving solution has a lot going for it, such as wide compatibility with popular archive file types, strong security features such as encryption, and plenty of support, including user and developer communities. B1 has most of the features that the competition offers, starting with Explorer menu integration. But B1 is easier to use than a lot of tools with similar capabilities, including not only the popular freeware but also some powerful shareware packages, too.

Installing B1 presents the user with a Welcome screen that starts with language options. A setup wizard walked us through each step, though experienced users can simply skip to B1's user interface. We used the wizard, which began by defining double-click action and includes options such as password protection and compression settings. B1's file associations include the most popular formats like ZIP and RAR as well as its own B1 extension, and it also opens 7-Zip's file format, 7Z. It's also possible to configure B1 to extract files to a preselected archive with a single click. The Welcome wizard closed, and we turned our attention to B1's well-designed user interface, which displayed a file list below an equally well-configured toolbar. Three buttons manage most of the action: Create, Open, and Extract, plus a Help button accessing an extensive Help file. We extracted ZIP and 7Z files and also compressed and uncompressed archives in the B1 format. Pop-ups simplify the process of setting up each step. We also like the B1 format's powerful compression ratio.

As we noted, we're impressed by B1 Free Archiver. Anyone looking for a good compression utility should give it a try.

"This is awesome! It needs more recognition."

Fast file compression and extraction.
Supports many formats.
Easier to use than other similar programs.
Elegant, nice look.


No option to extract from broken archives, or fix them, which WinRAR has.
If one file in an archive is broken, B1 considers the entire archive corrupted.
WinRAR seems a tab bit faster, but beggars can't be choosers.


B1 Archiver deserves way more recognition than it currently has. It's fast and easy to use. It is free. I work with some files which B1 confuses as broken, so I'd prefer WinRAR for advanced use. This is nice for extracting normal stuff like videos, though. It has support for many languages, and the setup's very fast. No optional software is offered (which is nice). Definitely download this, or 7-Zip, if you want a good and free compression software.

"Does the job, but is very suspicious..."

Can open .B1 files.


Everything else it can do, Winrar or 7zip can do much faster and without "downloading" stuff when you install/uninstall...


I downloaded this because I needed to open a .b1 file, and right away I noticed it was strange.

When you install, it apparently requires an internet connection to do so, and it takes a long time. Whenever you actually open and use the program, it takes awhile to load up, as well.

Also, if you unchecked the file extensions you didn't want to associate it with, well it doesn't seem to care.
It will make every .zip, .7z, and .rar open with this sluggish program by default, and you will have to go back and reset all of that manually. :(

When you uninstall it, it will have this weird "Downloading..." text on the uninstaller, like... What is it downloading? Spyware? Malware? Nothing should be downloaded when you uninstall a program, especially without permission or warning! I don't know if it actually did or not, because it didn't say where anything would be downloaded, and nothing happened after... well let's hope it's not a virus...

Overall, I do not recommend using this, unless you DESPERATELY need to open a .b1 file, and can't find any alternative.

I honestly do not know how it got so many 5 star ratings... Unless maybe people were bribed, or they have never ever used other safer archivers?
