I need to get about 15gb of mp3s and mp4s onto my flash drive. 7zip has a compression method that basically makes files a third of the size. Is there anything i should be wary of before doing this? Like will it make the songs not sound as good or anything?

It shouldn't make any difference. You may want to save a copy of the original, though, just in case something goes wrong.

 

Wrong forum, by the way ;)

As long as you keep it in ZIP the quality of your music shouldn't be compromised.

7-Zip may have some good compression methods, but almost no space can be saved on already compressd audio and video - in fact, even uncompressed WAV audio does not compress very well in most file compressors, unless they have a specific detected or selected "multimedia mode".

 

General purpose data file compression is lossless, so it makes no difference what kind of files you put in - except that some will compress a lot, others won't.

It may just be better to just fill up and empty your flash drive a few times, it'll be easier than zipping it all up.

From my experience, the files that compress the best are office documents. Movies and music get the worst results as they are already compressed most of the time.
