[New-bugs-announce] [issue46084] Python 3.9.6 scan_dir returns filenotfound on long paths, but os_walk does not

[Jim Schwartz]

New submission from Jim Schwartz <jschwar at sbcglobal.net>:

Python 3.9.6 scan_dir returns filenotfound on long paths, but os_walk does not.  I've enclosed sample scripts that compare the two and have returned the results.  the windows 10 registry entry to extend the path names fixes this issue (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled set to 1).  I've enclosed a scripts that proved this occurs and can be used for testing. I have a script that does the same thing using os_walk, but I can't attach two scripts to this Issue.
