While trying to backup my build folder I noticed a couple of errors that were down to permessions on the folder. After looking through the properties of the folder the "read only" box is ticked - but ticked 'grey' as though the permissions were being inherited. I took ownership of the folder, removed the inherited rights and added myself to the rights box, giving myself full control. I then unchecked the "read only" box and applied the permissions to all the folders beneath. The "read only" box is still checked when I look at the permissions again. If I go to the I386 folder and remove the read only permissions they stay removed so I then went to each parent directory and removed the permissions there. The only ones it doesn't work for are $oem$, $$ and $1. Is there some kind of issue with folders beginning with a $?. anyone come across this before?
