We had to add logic to block network and USB drives. (They were an ever-present source of customer issues.)
The root cause of the problem is that in .net, there is a bug with File.Exists. If there is a filesystem / network error, instead of getting an exception, the error is swallowed and the call just returns false. I'm not sure if newer versions of .net fix it or not; I only learned about this when we were implementing a driver / filesystem.

You can just mount network drives as folders
Which we detected and blocked, due to phantom deletions. (I explain the .net bug higher in this thread.)

doesn’t surprise me, network drive is the typical example of something that doesn’t “just work”.
