Anyway it is Possible:

Compress a 1GB file into a 5MB Size.

It is possible?

That would be quite a feat, but I really don't think its possible. If it is, I hope someone lets us know ... I'd be interested in that information.

Depends what you're compressing. If it's "the quick brown fox jumps over the lazy dog" a million times, I'd have thought that could shrink quite well. Most other things? Probably not. The likes of Ubuntu, Knoppix, etc. would have an easy life if that were possible!

I know I downloaded a 25mb program that apparently took 8GB in total when installed, so yeah, go figure.

Maybe if you ziped it, then put the zip in a zip, then put that zip in another zip, then repeated that 100s of times. I will try that.

EDIT: Zipping then zipping again doesnt work, the file size just stays the same.

[dawmail333]

I've tried that too.

[Sharky]

Repeatedly zipping will actually make the file bigger due to the file header, so that's not such a good idea.

[Zangetsu]

like sharky said it depends on what you are compressing and some programs are better at compressing then others

[Gouri]

using kgb archiver that can be possible but it mainly depends on data which you are compresing and the time to compress will depends on your system specifications.

Use KB archiver or hex edit it.
