Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
^[A-Za-z]:\\(?:[^\\/:*?"<>|\r\n]+\\)*[^\\/:*?"<>|\r\n]*$

Raw source: ^[A-Za-z]:\\(?:[^\\/:*?"<>|\r\n]+\\)*[^\\/:*?"<>|\r\n]*$

How it works

`^[A-Za-z]:\\` matches the drive letter and root backslash. `(?:[^\\/:*?"<>|\r\n]+\\)*` matches directory segments. Final segment (the file or folder name) is allowed to be empty.
