I am having a very hard time trying to work psp, even when i read tutorials its not working how i need it too. I also had some free download props of heads, etc. they looked like a zip folder but were not , and i couldnt open them in psp or microsoft paint of viewer. Nothing would work, any suggestions?

To unzip folders you need Winzip.

Google is your bestfriend. To open rar files you need 7zip. It is another compress file.
