When you purge mods, it usually leaves folders behind. Lots and lots of empty folders with "__delete_if_empty" as a marker I guess manual deletion. But, there's lots. Lots and lots of these folders, and right down the bottom, there might just be a hand-edited file I stuck there at some point. It was so long ago, I have no reason to remember I put that there. But, looking at the folder structure from the top, there's no mechanic to suggest there is that useful file all the way down there, unless you go and explore it by following the trail.
Am I doing something wrong? Is there an external program that could search through and highlight if there are files remaining after a purge? It's likely I'd like to keep those and reinstall them after deployment.
Right now, I'm just leaving everything there, as messing and disgusting as that is, and not really worrying about it. But, what happens if on deployment, the system wants to overwrite one or more of these hand-edited files? Will it do that? Do I have to worry that it will just erase my work like that?
