The path module has a few different functions: Clean, Split, Join, Ext, Dir, Base, IsAbs. These functions do not take into account the OS-specific path separator, meaning that they won't behave as intended on Windows. For example, Dir is supposed to return all but the last element of the path. For the path "C:\some\dir\somewhere", it is supposed to return "C:\some\dir\", however, it returns ".". Instead of these functions, the ones in filepath should be used instead.
