According to the website, it handles these formats:
- Packing/unpacking: 7z, ZIP, GZIP, BZIP2 and TAR
- Unpacking only: ARJ, CAB, CHM, CPIO, DEB, DMG, HFS, ISO, LZH, LZMA, MSI, NSIS, RAR, RPM, UDF, WIM, XAR and Z.
I have used it for at least three years to pack and unpack *.zip and *.tar.gz files on my Windows boxes. Recipients of zip files that I packed with 7zip were able to unpack them with Winzip or other unzippers better known than 7zip. (More about Winzip here).
I have also to used it to unpack *.rar archives, including some that were over seven gigabites when reassembled. It has not missed a beat for me, except when the archive itself turned out to be corrupt when tested with other unzippers.
(Aside: I also have registered versions of WinRAR for both Windows and Linux. *.rar is the native WinRAR format. Yeah, I wish they’d rename the Linux version to LinRAR, but, oh, well. More about WinRAR here.)
At time of installation, 7zip offers the option of integration with Windows Explorer, so that, when you navigate to a file in Explorer and right-click on it, “7zip” is an option in the pop-up menu.
You can learn more about it at the 7zip website.
