The fsutil command line utility has a number of useful diagnostic and configuration tools for the Windows filesystem. Making a file of an arbitrary size, possibly very large, with this utility is very easy. Making a 1GB file with other methods (wordpad?) can be .. tedious.
To create a 12000 byte file called file.out, use this command from the command line:
fsutil file create file.out 12000
To create a 10GB file, use:
fsutil file create bigfile.out 10737418240
