bzip2 is best at everything I have tried. I have tried text files,
executable binary files, etc, and bzip2 always compresses considerably
better than the others, and pretty fast.

I'll write a detailed description (as always) when I have coded it... :)

What kind of data are you compressing? bzip2 is usually slower than zip
at compressing and about the same speed at uncompressing.

Zip is well-documented, patent-free, and there is an implementation with
a very lenient licence. This is probably the reason why it is used for
compression in almost all internet protocols and file formats of the
last few years. The fact that many Web servers are Unix machines and zip
is available on these machines, while other formats often are not, may
also have had some influence.

bzip2 doesn't even exist for "a long time", AFAIK. It is certainly
younger than Windows95, so a 32-bit environment should not have been a
problem in in the Windows world.

But I *reeaally* want to know it now so I can come with comments and
suggestions in the development stage! :)

Create a .pif file for it and associate your action with the pif file instead
of the bat file.
