This is a common mistake.

When you first download the file from the WreckDisk Website, you must save it to your Local Disk C: in a place where you can find it after the download. A good spot might be saving it to your DeskTop.

Be sure that you don't accidentally rename the file that you download.

After the download completes, you must then RUN the downloaded file. If it's on your desktop, simply find the new Icon and double click it.

You will then be asked to insert a blank floppy disk into your A: floppy disk drive. The program will then create you new boot'able WreckDisk.
