- You can create a file of any size using nothing more than what's supplied
with Windows. Start by converting the desired file size into hexadecimal
notation. You can use the Windows Calculator in Scientific mode do to this.
Suppose you want a file of 1 million bytes. Enter 1000000 in the calculator
and click on the Hex option to convert it (1 million in hex is F4240.) Pad
the result with zeroes at the left until the file size reaches eight
Now open a command prompt window. In Windows 95, 98, or
Me, you can do this by entering COMMAND in the Start menu's Run dialog; in
Windows NT 4.0, 2000, or XP enter CMD instead. Enter the command DEBUG
BIGFILE.DAT and ignore the File not found message. Type RCX and press
Enter. Debug will display a colon prompt. Enter the last four digits of the
hexadecimal number you calculated (4240, in our example). Type RBX and
press Enter, then enter the first four digits of the hexadecimal size
(000F, in our example). Enter W for Write and Q for Quit. You've just
created a 1-million-byte file using Debug. Of course you can create a file
of any desired size using the same technique...
