No access to Sesame now, but this may help:

You could use DIR command.  Redirect it to a text file, then parse the file for the date at the beginning of the line.

Example:
DIR filepath\test.txt>tempfile.txt  is the line for RedirectProcess

This is the result in tempfile.txt:
Directory of C:\Documents and Settings\Bob

01/29/09  06:39 PM                67 test.txt
              1 File(s)             67 bytes
              0 Dir(s)  18,695,352,320 bytes free

The file date for text.txt is at the beginning of line 3.  So you could use RegExBetweenString or read the third line and take the left most 8 characters.  Format of the date may vary depending on your system settings.

You are right Mark.   

I am still an old DOS user, hard to break those habits.
