Dummy File Creator

Darn those Virus and Trojans... You just can't get rid of them huh? Let's talk about preventing infections rather than curing it.  While browsing the web I found this neat software that can be used to create dummy files to your drives.


How can a dummy file help in preventing infections you ask?

A dummy file can fool viruses from infected computers that a drive or storage device is filled with data and therefore that virus cannot infect that drive anymore.

This is not only the case, a Dummy file creator could also do the following:

  • Prevent easy spread of illegal copies of your software - Imagine you just publish a new software with a size of 56MB onto a CD. You can fill the the remaining 644MB free CD space with fake files. If you cannot stop the crackers, you can still slow them down. People who try to transfer your software over the internet will have to spend longer time, while the authentic users who purchased your CD will not be affected.

  • Fool people on peer-to-peer file sharing networks - Although most peer to peer network programs have built-in CRC/Hashing check to prevent malicious fake files, a person can still share fake files with the same file name or catching program/media title to confuse P-to-P users.

  • Enhance protection of exsiting encryption - put a few fake files with randomly generated content along with your encrypted files. Investigators will have tough time finding/decrpyting your files, since they won't even know which one to start with!

  • Test drive fitness - simply fill up the drive with a large dummy file. Any bad sector will result an write error.

  • Wipe data to prevent file recovery - Have important data that you want to make sure it's deleted beyond recovery? Simply fill the drive after deletion/formation with a large dummy file. Normal file deletion or disk formation procedures only modify the file allocation table (FAT) to make the space available for writing without actually removing the data, so it makes data recovery possible by scanning through the entire disk to look for remaining data traces. By filling up those available spaces with dummy file contact, it overwrites all the those data traces with dummy file content.
