I Have a problem, the MY MUSIC folder has grown so large that my hard drive is almost totaly full,
my question is can i use win- zip to crush the my music folder so as it takes up less space, or should i do them each singly? or is it (as i suspect) not possible to compress mp3 audio files or folders??
The simple answer is yes, you can zip the my music folder. But you can only do this if you have enough space on your drive to do so. Wouldn't it be better burning all your mp3's to cd audio or data disk. To be honest the space saved wouldn't be worth it to zip this folder, and as your drive is nearly full it would be better removing them all or at least the ones you don't need.
You cannot reduce size by compressing MP3 files and also wave files. Mp3 is compressed format, even go beyond it, it is actually lossy method of reducing file size by throw away some information. This means that you cannot get the exactly the same wave file when you "compress" a wav file to mp3 file and "uncompress" back. This is not the same as zip which is lossless compress method, i.e. you can get back original.
The original wav files (ripped from CD) cannot be compressed by any lossless compression method.
If a music file can be compresses, why clever people invent mp3 in the first place.
Of course, you can re-encode mp3 file using low bite rate to reduce file size. But you loss quality by doing this.
