Best way to back up/compress my music files?

There's so many people like you asking about these compression wonders like "compress to less than 1% of original size" or "super compressor". There's no such thing and it's not physically possible. Go buy an external hard drive and put your songs there.

Jeeze. MP3s don't compress well... most multimedia formats don't. 175 GB? WOW.

Okay.. well if they're in AIFF format (straight from your CDs) then convert them all to 128 kbps MP3s, and you'll have about 6 GB of music instead of 75.

If they're already MP3s (if so you've gotta have probably what, 20,000 songs?) then you can try converting them all to 128 Kbps instead of whatever they're at now. If they're at 256-320 Kbps encoding rates, you'll save 50-60% size.

while you're speaking with regard to the "six strikes" gadget, that's on condition that they seize you, and that i'm particular the RIAA could nevertheless convey a lawsuit against you in the event that they had to. It on no account has been legal to get carry of copyrighted textile without the permission of the copyright holder.

Right Click on the folder that contains all the music, and Compress :)

If not your choice. u can google a compressing utility to do it :)
