Hello. I'm just wondering about the "Compress" option when you right-click anything in the "Finder".. I know that it makes a (.zip) file of whatever you select..

Does this compression cause any reduction in quality? I have a TON of (.wav) and (.mp3) libraries that I would like to compress for storage purposes, but it is extremely important that there will be no loss in sound quality or file integrity..

Yes, zip file compression is lossless. But it may not do a lot of good. WAV files are compressible. But mp3 and video are usually not very compressible with zip. If you have a lot of mp3 and video files, you aren't likely to save much disk space.
