Accessing file

what type of file?
Excell? word? office doc? PDF? notepad?

why would that matter?

Excel, notpad, and *.7z files

I'm not familiar with *.7z files.
because this problem involves several different types of files I suspect there may be some kind of encryption involved, however thats a wild stab in the dark.
If you hang around we have some techies who pop in once or twic a day perhaps they can help.
What is the exact wording of the message you recieve when you try to open the file(s)

Thanks guy, but any idea how can i get the file open?
