.uha files? How to expand?

Iam not sure what format this is and where it came from either.
After doing a check on this site of every format used, it appears they aren't familiar with this format either.

Please what type of file is this and what program generated it.
It seems that it may be an obscure file generated by a program or game.
Please tell us more about this file.
Cheers Don

It may in fact be better than some of the Industry Standards on the Market, but as you point out it is for Windows. and not usable for MAC Operating System
I question a couple of things. (Windows) WinZip is Free or Shareware.
Stuffit Expander is also Free, and comes with Mac OS
I may be confused why would one pay for a Utility to Expand or create a Compression of a file that I am not sure of it's use.
I am not an expert, but it almost sounds like this is a Developer trying to create a new Utility used for compression and de-compression,
I would stear clear of these until you know a lot more about it.
Both of those I mention above seem to be more or less the Industry Standards and they work and work well, why would you want to use something different.

anyone found an app that can do this on os x maybe?

UHARC Compressed Archive

Note that the .UHA format can, in some cases, be version specific so one version of the program may or may not unarchive an archive created with a different version. In case the 0.4 version doesn't work try searching for version 0.2 and see if that does.

I can't find any *NIX programs for this format...

Only Windows apps...

I just received a .uha file myself and have been searching for a way to open it. Now the file I received also had a .exe within it. So I decided to open that on my PC. Turns out, the .uha is an encrypted file and this software stated, if I wanted the password, to pay $1 via this .exe.

So I think it's a format written to attain revenue. I can't really make sense of it and am not willing to pay, since I suspect any .exe to be some form of spyware, which it very well could be.
