note: (some versions of?) robocopy appear to have a bug where the local time
zone is used with the wrong sign, causing it to log timestamps that are out by
2*abs(your locale's difference from UTC). e.g. for Pacific Standard Time,
robocopy's timestamps are 2*abs(-8) = 16 hours off.

list all paths (including folders & empty folders), but no timestamps (because
of a bug/inconsistency, robocopy only prints timestamps for files, not

robocopy .\targetdir NULL /L /E /NJH /BYTES /FP /XJ /R:0 /W:0

list only files, and include timestamps:

robocopy .\targetdir NULL /L /S /NJH /BYTES /FP /NC /NDL /XJ /TS /R:0 /W:0

Explanation of switches:

                 /L :: List only - don't copy, timestamp or delete any files.
                 /S :: copy Subdirectories, but not empty ones.
               /NJH :: No Job Header.
             /BYTES :: Print sizes as bytes.
                /FP :: include Full Pathname of files in the output.
                /NC :: No Class - don't log file classes.
               /NDL :: No Directory List - don't log directory names.
                /TS :: include source file Time Stamps in the output.
               /R:n :: number of Retries on failed copies
               /W:n :: Wait time between retries: default is 30 seconds.
                /XJ :: eXclude Junction points. (normally included by default;
                       note: due to severe bugs, robocopy does not support junction points).
