A Version 4.64 of the free 7-Zip archival utility has been released. This version fixes a bug related to decrypting .zip archives.
 
For a FREE (sorry about that) program, this one has to rank as a gem. Lots of features, fast, and easy to use. And one of the best pieces of Freeware around. Can't ask for more than that, can we?
