What kind of files are these?

I recently extracted some files from a newsgroup & it gave me these three type of files:

xxx.uha
xxx.bat
xxx.exe

I ran the .exe file, but nothing happened. I've extracted files from newsgroups before, but it usually gives me some sort of burnable file (.iso, .cue/bin, .mda, etc.). I've never gotten these types though. What do I do with these files now?

 

.uha is a compressed archive.
