A while back I had gotten a program that was free to open zipped files but it didnt' just open one at a time it opened alot at once. anyone have any idea what program it may be? what programs do you all use to zip and unzip your files?

I lost my hard drive and all the programs I had on it and just can't remember what one it was ugh...so frustrating. Any help would be greatly appreciated.
Thanks and have a wonderful week!


PS. the program I am looking for open more than one file at once.
