Some people just want the moon on a stick.

When you compress a file, all it's doing is compacting a load of redundant data in the file(s) in question.
There is no guarantees that a file can be compressed in this fashion because its all dependent on the amount of redundant/slack data already present. This explains why executable files (which are already tightly packed) compress by next to nothing and text files compress quite well.
Windows Bitmap files compress really easily (up to 99% in most cases) because they contain so much redundant data inside them, which also demonstrates wonderfully why you should save them as JPEG files for image purposes on the Internet but that's another topic.

So basically, depending on what you want to compress, nothing may be able to compress a 200Mb file to a 50Mb file.

As Neil said, it depends greatly on what you are trying to do. If you told us what your trying to compress, it would help.
