I wish he would fix the shell integration on windows. I really hate when 7-zip suggests to expand files that are not compressed files. That's what keeps me from using it full as my sole software for compression.

There was a guy that solved it for the developer a few years ago for a couple of versions but Igor didn't use the help so he stopped. He only seemed to care about the compression ratio.

Other than that, superb!!

best FREE compression program out there in my opinion ;)

to bad it dont tune it's interface to be a little more simple like WinRAR... but other than that it's hard to complain overall.
