Thanks you all who helped me to make the selection. I appreciate all your answers. Anna
I use Free RAR extract frog-google it.I installed it years ago & it automatically unzips all the rar files & I delete the ones I don't want & the original still has all the files zipped . I keep all the zipped files incase of a meltdown or a change of machine
WinRar is fantastic. Love Chris
I found through cuties, 7zip . Very easy to use
I use ExtractNow which is a free program. I works fast and I can unzip or expand many files at the same time. You can just drag your files onto the little window and it expands them. You have a choice if you want them in an individual folder. I keep a shortcut to it in my bottom bar. However, I still have Windows xp so I am not certain how it works with Win 7 but I would imagine if you google it, it would say if it does.
