Unix Executable File Trouble

Hi Guys,

I have a folder on my USB memory stick that contains some important information which I need to access. I logged onto my computer this morning and opened up the USB memory stick to find that the folder with the information in has changed to a 'Unix Executable File'.

How do I change this back? I have read through a few places and people have said about buying different products but i'd like to do it without having to pay anything extra if possible.

I do have backups but they are over 300 miles away from where I am!

Thanks

Open a terminal and go to the file
This will change permissions to
rw-r--r--
You can verify this by doing a ls -l in the proper directory.
