How to delete all snaphosts in Virtualbox?

I have till now everytime saved and loaded machine from snapshot, but my SSD disk now is full and I can't do anything. Snapshots folder are using 70 GB and what I want to do now is delete all snapshots and everytime turn off machine and then turn on without snapshots. Is there any way to load last snapshot state into machine and delete all snapshots?

The ability to delete all snapshots has been requested on Oracle's enhancement & bug tracker, and also in Virtualbox's forums. Sadly, AFAIK, this is still not possible to do; out-of-the-box.

There is, however, a solution!

In the form of some Python and XAML source code: VirtualBox Snapshot Deletion GUI.

You will need to compile this into an .exe file to run it. Information on how to do that can be found over at Stack Overflow: Compiling an IronPython WPF project to exe.

The author of the tool believes it would also be compatible with OS X and Linux hosts.
