Usage
The website above also includes a tutorial for using the software. In essence there are two important aspects you must remember:
1) Choose the correct memory card
In the uppermost drop down menu, you may choose between all available memory cards on the computer that runs the software. If you choose the wrong card, you risk loosing data permanently.
2) Chose the right formatting
Make sure that Owerwrite format is chosen. This usually takes much more time than Quick format, but is the only method that ensures proper deletion of the memory card. A card with the capacity of 16 GB, takes about 15 minutes to delete securely.
