Hi,
after recently reading somewhere about compression ratios - it says certain types of files can be compressed to a fraction of their original size.
One such file type are bmp (bit mapped images).

My question is do any of the users on this site know of other file types that can be compressed so much?

for anyone out there who plays football manager 2007 - if you wants to back up your game saves (winrar them and they are compressed to a much smaller file).

I use Winrar primarily. What is best compression softare(s)?

P.S
does anyone know how to compress movies on a hard drive?
they take up far too much space.

Thank you.

i use divx pro to compress all my movies
