My old Win Xp Laptop broke so I'm using the hard drive as an external for my
new Vista Laptop, but whenever I try opening files from it I'm getting
trouble with permission.  

I have tried changing permissions on the security tab of properties but not
having much luck, although I had a bit of luck with idividual files within
folders but cant for the life of me work out how to set it for whole folders
and subfolders, and now I'm going around in circles getting more frustrated
with this whole thing.  

Anyone shed any light on a simple solution or have I got to go through
setting the security permission for every idividual file?

Regards
