SO i have a maximum scope depth tool, that i just put together it is super simple.
but when i use it in a drive other that C:\ i get an error. Even though i just checked for a valid path.

Any ideas?

Looks like its a bug with WinAPI.

From https://dlang.org/library/std/path/is_valid_path.html :

> It does *not* check whether the path points to an existing file or directory; use std.file.exists for this purpose.

You are using the wrong function for the job.

The simple explanation is that the path you specified doesn't actually exist.
