Not an answer to your question, but an alternative solution.
Try using the following command at the DOS prompt :
A:> REM > filename.ext

Then use IF EXIST filename.txt to test for the existence of the
file.  The above method will create a directory entry only on
the disk, and does not take up any room on the disk.
