Pocket RAR is able to compress, decompress and delete files in RAR and ZIP archives.
It does not provide many advanced functions available in WinRAR, for example, archive repair or authenticity verification.
Such functions were removed to make the executable size smaller and reduce amount of precious Pocket PC memory occupied by the archiver.
Advanced archive processing can be done on the desktop computer having more memory and faster processor.

Exe's don't work on PPCs. Why is this even listed for pocket PC if there is no .cab installer? Man, I'm really starting to hate rar's.

For those of us without a computer who use ppc exclusicely for internets... Completely useless! Please upload .cab insaller.

If you don't know what a .cab file is, you have no business using a pocket pc!

Good solid program for opening or making RAR or ZIP archives, just like the desktop one. Only two drawbacks: (1) updating a RAR archive seems to be impossible: despite 20MB of free memory it failed to update a tiny 10KB RAR archive! (2) The seamless way its file explorer drops in and out of archives can leave you confused as to whether you are looking at real files or the archive - this could be dangerous, they need to make the distinction more obvious.

It would be a great prog, if there were a cab installer file.

I have been looking for a good compression utility for a while now. This is JUST GREAT. Both Rar and Zip files... easy and light program. Well done. LEGEND!

It's one of the best compressors ever. I RARed my whole website into my pocketpc! and saved 60-70% space!

I don't even know what "CAB" is. But I load this without any problem and it works...!! Thanks.

This program just rocks! But a PPC CAB based installer would be a great option.
