I've done a search resulting in my head is in a spin.

What I want to do is to search a partition for files with the same name, that is, in all the folders in the partition and not to replace them, i.e. simply delete the file.
The file is Blueprint.bak and its in RailWorks simulator program folders.
When a route is installed there is that file in a lot of the folders, if they are not removed the sim won't run.
I've tried a few things but I can't get anywhere really.
Looking at the commands I had a look at IfFileExists, due to my lack of knowledge in this area of computing I have not got anywhere.
Can anyone assist please.
Thanks in advance.
Ian
