EC, download 7 Zip and/or IZArc. They are free and will extract most any type of compressed file. Make sure you d/l the correct version for your Win 10 (64 or 32 bit). Both WinZip and WinRar are trial versions with nag screens unless you pay. Youtube is usually good for instructions and kitty videos.
