-**NOTE:**  It makes the path conform to the NTFS standard (see the MSDN spec).
-  * **<nowiki>^[a-zA-Z]:\\</nowiki>** matches single drive letter, with colon and backslash
-  * **<nowiki>(?![<>:"/\\|?*])</nowiki>** is a negative lookahead to ensure the next character is not invalid
-  * **<nowiki>((?![<>:"/\\|?*]).)+</nowiki>** wraps that lookahead, followed by the next character, any number of times
-  * **<nowiki>(?<![ .])\\</nowiki>** is a negative lookbehind to ensure the file/directory doesn't end with a space or period. Please note: Lookbehinds are not fully implemented everywhere just yet.
-All of that is is repeated 0 to many times, with the last backslash optional.
-For many use cases it may be best to restrict the path length to 256 characters.
-  * To do so, replace <nowiki>*with {0,256}</nowiki>.
