WinRAR has one feature I wish 7-Zip would add. When selecting multiple zips, you can extract each to their own subfolder with a single command. I miss that more than anything.
You can do that with 7Zip as well, its a part of the context menu for that.
Yep, it even names the folders after the zip files' name. Right click, 7zip >
"Extract to /*"
This must be new! I've got my context menu customized everywhere I go might be why I missed it.
