Test File  Maker !

Test File Maker is a simple program designed to make dummy files that you can use for testing purposes. It supports several modes of file creation (see below) ranging from the very fast to completely random. Test File Maker can make files suitable for testing compression / encryption algorithms; for measuring download / upload speeds on a network; for testing disk I/O throughput; or any other situation where you need to use a file of a specific size.

No Data (0x00) - Every byte in the file is set to zero.
Random Data - Each byte in the file is set to a random value. This creates a file that cannot be compressed well by patten-based algorithms.
ASCII Test - A patten of standard ascii characters is repeatedly written to the file until the target size is reached.
Truncate (Set Size) - Space is allocated to the file but no data is written. This method is VERY fast as it only allocates space for the file. However as the data of the file will be whatever was on the disk already this could be a potential security problem for you.
