Reply To: Zipping, how much will it save?

from the responses here i was able to google more accurately.

i found out:

1.in general 7-zip is probably much better than winzip as todros said

2. for jpeg files winzip Vers. 12-15 has a special algorithm that compresses them about 20%. i dont know if 7-zip does this.

3. i wasnt able to get any specific info on mp3 files except that they dont compress much as was said
