As Walter Roberson mentioned, this is impossible with dir(). One could use Jan's solution though that was not appropriate in this case. I ended up using shell.

Hi there,
I am looking to extract the timestamp (specifically, the "modification date") of some files in a folder. If I use dir(), then I can get the modification date in either datetime or datenum format. However, both of these give the timestamp to second precision, but I know the actual timestamp has millisecond precision. I want that millisecond precision. Is there any way to get the timestamp with millisecond precision using dir()? If not, how can I do this?
Thanks in advance!

@supernoob: The function GetFileTime can reply the time in the native format as stored in the file system as UINT64 counted in steps of 100ns. Then you can convert this how ever you like it.
The C-Mex function uses the Windows library function FileTimeToSystemTime, which rounds to milliseconds.
