⚠️ Disclaimer⚠️ This application was created for educational and learning purpose and is not intended to be abused in any form. The original idea of this application was to pull a prank on a friend of mine.
I am not responsible for any damage or system failure caused by this application. Only use it on your own systems or with explicit permission of a devices owner.
The application hides itself from the taskbar and has no window. It is closable by the Task Manager.
-
It checks if there are at least 4GB of free space.
-
After that the application copies itself to
%appdata%. Once copied there, the current process will be closed and the file will be deleted. -
Next step is creating a folder within
%appdata%which contains a GUID. That folder will be used during runtime for the creation of new files. -
Each file contains ~500MB of data.
-
There are 5 Threads in total which each create multiple files per second.
How long does it take a disk to fill?
When I tested the application on my systems, it filled about 1GB per second.
In my case a 1TB C:\ disk would take ~16 minutes until it is "full".
ℹ️ Performance might vary throughout different systems
Why does it check for 4GB of free space?
It is not necessary, but I thought to myself, to leave some space available for the operating system itself.
I did not really test what would happen at a complete full C:\ disk, but maybe this will be changed in the future.
How can I fill a disk much faster?
This could be achieved by starting multiple threads or increasing the size of the file content.
Why is this application blocked by anti-virus software?
That might be because the application has sort of a malicious behaviour:
- The application has no window (size 0x0)
- The application itself is not visible in the taskbar
- The application writes much data to multiple files
