Ok makes sense..
I take it this is just a link rather a direct relation to the file??

The reason I say this is if I delete a dark entry I am left with the light entry and it plays just fine even though when I deleted the dark entry the system stated that I am deleting the file from hard disc and it will be gone forever etc.

That's what didn't make sense. So I take it it is just deleting the link to the entire file and what's left is a symbolical link to a portion of the file????

Thanks much
