Python's os.path.realpath, when used with a substed drive on the Windows platform, don't resolve the substed path to the *real* path. For example creating a substed drive like this: subst z: C:\Users\Public\Desktop and checking for the real path in python like this: import os myPath = "S:\\" print("Real path of: " + myPath + " is: " + os.path.realpath(myPath) ) prints Real path of: S:\ is: S:\ In the docs for the [subst][1] command, a substed drive is referred to as a *virtual* drive. Virtual, suggesting something being "not real", indicates that the Python *realpath* command is not working properly on Windows.

In Windows, realpath is currently an alias for abspath. Issue 14094 has a pending PR that implements realpath, but it's waiting on improved tests and final approval. I'm afraid it won't make it into 3.8. I suggest using the resolve() method of a pathlib.Path. For example: >>> os.system('subst W: C:\\Windows') 0 >>> pathlib.Path('W:\\').resolve() WindowsPath('C:/Windows')
