yup, done that. I use Ztree for things like that. It knocks all the windows file managers into a cocked hat. I've searched every file in the relevant directory tree and still fail to find what I'm looking for. I've got an example right now. Trivial and incosequential but really irritating.

Whenever I go into one particular project I'm working on, I get an error message telling me it can't find an icon file. It doesn't even make the same protest when I compile the exe. This must, somehow be associated with the project, yet even with a hex search, I can find no mention of it in any related file...

grrrrrrrr....
