5 Ways to Create Dummy Files

Print Page

Here are five ways you can create a file that looks legitimate but is actually a dummy file. But why would you want to create a dummy file? Here are five reasons for that:

  • Test hard drives – Detect bad sectors on your hard drive by filling up free space with a dummy file.
  • Securely delete files – A deleted file can be recovered but by overwriting the free space with a dummy file will make it unrecoverable.
  • Secure Flash Drive – Make your flash drive read only by filling up empty spaces and prevent virus infections.
  • Test network speeds – While there are free utilities available to test network speeds, you can do so with a dummy file too.
  • Dummy files can also help you escape a deadline  you’ve got to prepare a report or finish your homework by putting the blame on your faulty computer.
