can some1 tell me how to highly compress files with 7z?i mean 1gb files to end like 100 mb files...

i just use the "Ultra" option

 

for example, i have the folder of C4 compressed like that, 4gb to 1gb

you can download 7zip too

why dont u just choose .rar or .zip?:?

you can download 7zip too

7z = 7zip extension

7z have better compression, much better, a lot!

well you can also use UHARC.

 

search for it in google. i made gracia final from 4.7 GB To 500 MB

 

cool? xD

from what i read, KGB Archiver its better that 7zip and that UHARC

 

but this kind of compresor needs too much RAM and then, too much time to descompress the file
