7z -- what's it?

[bellgamin]

I got a file in format 7z (file name kmel.7z), which appears to be some kind of compression scheme. Does anyone know what this is? Better yet, does anyone know what program I need in order to uncompress a 7z file?

If you don't like 7zip original program than you should try another file archiver that support 7zip files:

QuickZip
http://www.quickzip.org/

TUGZip
http://www.tugzip.com/

IZArc
http://www.izarc.org/

You can use WinRAR to unpack 7z as well.

It is not free, but PowerArchiver is really good. Have been using it for years and really like it.
