USB Dummyprotect is very simple to use.
- Download and copy the software into your USB drive.
- Execute the file from USB drive in a virus free environment. [at your computer for example]
- It will create a dummy.file and it takes all free space in your drive.
Note: Of course it would not protect from everything, but help in most cases.
Moreover, it useful only if you need to read files from your drive, if you need to write something to it you need free space on USB drive and viruses could use this space too.
It wouldn’t work if there is more than 4GB free space on FAT drive.
