The BZ2 file format is usually used for Linux or UNIX systems and can only compress one file at a time. It cannot be used for multiple files.

You can though compress multiple files using a different tool and afterward get that final archive and compress it with BZIP2.

Even if BZIP2 is not used in Windows 10 as much as on the other mentioned operating system, there are ways to decompress the BZ2 file.

In this article, we will show you some really easy ways to extract and decompress BZ2 in your Windows 10 device.

How can I extract and decompress BZ2 files in Windows 10?

1. Use a dedicate tool

There are many tools out there that will allow you to decompress and extract BZ2 files and after testing them all, we would like to recommend you the best one to use.

WinZip is a versatile tool that does not only open BZ2 format files but many more others, such as RAR, 7Z, ISO, IMG, TAR, GZ, TAZ, TGZ.

This complex software supports all the above formats but is more than just a simple compressing and archiving tool.

WinZip can also repair zip files, manage them and in addition to all that it comes with a very strong security feature.

The almost bank-level encryption feature will make sure your files are safe even while compressing them.

If you are sharing them online or sending them via email, then you can rest assured that at any moment your data is safe and secured. You can password protect your archive and opening them without it would not be possible.

If you will prefer to protect them using a password, make sure to use a password manager tool, just to make sure that you will also have it at hand any time you need it.

This amazing software makes sending large files via email possible. Most of the time this is a great concern for all members of a team when they need to share a large file.

What WinZip will do, is break the big file into smaller chunks (in case of ISO image) without affecting the image quality in any way.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.
