Compress a large data file

Can I compress a data file of approximately 25Gb and which software/application could I use?
Winrar and Winzip seem to take ages to do the job and there must be another application that is more efficient.

Look, you can use:
winzip
winrar
winace
7zip
bzip2 (if unix/linux)
gzip (if unix/linux)
some others...

But no matter the one you choose, it's almost the same algorithm at the end.
You have to choose a compression/speed ratio and decide what you want : real smaller file or not ?
Example with winrar, in the options : "create default profile" and you choose something different from "best", it should be faster, bug a bigger file at the end.
It also depends on your file content: text, raw data, something specific ? Some content will require more time(/techniques to be correctly compressed.

You can't just ask these tools to "do it faster".

By the way, maybe the idea would be to have something to cut your file into smaller pieces (1 GB parts). Thus, you might be able to multi-thread your process (depending on the disk speed/interface and so on.

If you want some help to decide: tell us what's this file, how it is generated and so on...

Thank you very much,I will stick with Winrar and be patient for the RAR file to complete.
I just wanted confirmation that I was on the right track........
