How to tell which program is accessing a file..

[Gimpymoo]

I am currently unable to delete a file from within Windows as it is reported the file is in use. I have restarted the computer however no success.

It is merely 1 part of a compressed backup set.

Can I use a program to determine which files are currently being accessed and by which application?

Many Thanks.

The file was mounted in Daemon Tools
