Can someone recommend a FREE open source archive file opener like RAR that is easy, intuitive, and does NOT need or use a password. I tried a couple of them and both needed a password which is NOT one I make up but one that is assigned to the file from where it is downloaded. That password was not displayed anywhere on the site for me to enter in the program. A bit overkill. In the alternative a file converter that would allow the common extentions to be read in ADOBE READER would be ideal. I do not often use RAR and the like but it would be good to have the ability. ZIP files CAN open using WINDOWS. The file is saved as a ZIP, selected, and it opens in the ZIP EXTRACTOR page. Simple. a similar program for RAR and the like would be ideal.
