When saving a file and the filename begins with a number, a dialog box pops up and mentions that there are potential compatibility issues with the file name if it does not follow Python naming conventions for use outside of JES, but does not mention that a filename cannot begin with a number although it does catch it as an error. Due to my like of saving files by a YYYY_MM_DD format, I just added "D" for date and no more compatibility issues.
