Reduce File/Folder Size by compressing

[Ajrick14]

Hello,

I know how to compress files with different archivers and I have used winrar, 7zip etc to compress files but what I really want to know that how can I ultra compress files to reduce their sizes, I have searched a lot on Internet but haven't found anything working for me and I have seen some devs,  they can easily reduce the size of a 16 GB file/Folder to 13 GB or less. I know it depends upon the file also so please suggest some procedures

Thanks in advance

Here is one to check out....System Navigator File Manager and Compression Utility

Uses 13 different file compression formats.....
ZIP, 7z, TAR, BH, Bzip2, CAB, GZip, JAR, LHA, TarBz, TarGz, WIM and XZ.

keep in mind the more you compress a file the more chance for corruption

I use 7zip but compression will depend on what type of media you are compressing
