Ok RAR is heresy. The worst thing to ever infect your computer. Once you download that stupid free program, it destroys every thing on your computer as it without your input CONVERTS every freaking jpeg you got into RAR for mat and you can never ever fix it. Just get CS3 and do your work in that.
I have WinRAR on my computer (the free version) and with any freeware, i’m always very cautious about auto-setups… there’s options to basically disable everything in WinRAR and have the program ONLY work with RAR files, which is exactly what I did.
I’m no fan of RAR… I don’t like the format, but sometimes you gotta deal with people that live by that, and if they have a file you really want that is RAR-compressed, you gotta do what you gotta do. If you get WinRAR, just make sure you do a customized install and disable the program from everything but RAR files.
