Xp onwards has this built in?
Are you trying to unzip? Or zip up lol? If unzip just double click the file.
7 zip is fantastic handles everything i chuck at it
7zip is freeware and awesome, reads everything ive ever needed uncompressed, also if you 7zip something up the compression ratio is quality!
No you don't, you just click "OK" every time it prompts you to buy. 7zip ftw thoughYou'll have to pay if you want WinRAR
