Hi there anyone knows what compressor is best to use, I mean now I'm using winrar but my problem is it just make the file a little smaller in size, I need (if there is) compressor that compress about half of the file size... :D

You will be fine using winrar or similar, Unfortunately you can't always compress files by the same amount. Some files will compress to a fraction of the original size but some will hardly change. It is all to do with the original contents of the file.

Think of it like using a vice, if you had two different things to squash like an apple and a piece of coal you would expect the apple to squash down to a smaller size than the coal because it is softer and contains water etc.

Anyway hope you understand the meaning in all this tripe, some files compress more than others.

Hi,
I like EnZip, from:

But, I don't know if it will compress any better than the one you now have.

That's the problem when I'm compressing a KB file it compress a lot amount but when it comes to MB or GB it only compress a bit...

Hi,
Try 7-zip. You can download it from the below link. The compression ratio is much higher than Winzip and Winrar.
