I don't think there is an easy way of doing this.

What I have used in the past is the following command (from c:\)

DIR *.gid /s /w >temp.txt

This will list all the gid files, and save them in the temp.txt file

However, you will now need a program (any language like perl will do, as the output from this is very easy to process) to read the temp.txt file and change it into a series of DEL commands, which you can then execute as a batch file.

If you only have a few, then you can just print out or view the temp.txt and delete them manually.
