There should be a way to make Recuva minimize to the system tray while doing long secure delete operations. Right now the popup window that shows the progress bar and stuff prevents you from minimizing it through the main program's window.

You can either allow the main program to be accessed also or make the popup window go away and move that info next to the scan button in the main interface.

While in the system tray if you put your mouse over the icon it can popup a little hint box that shows the current progress percent or something.

I could be wrong here, but wouldn't it defeat the purpose of recovering files if you running another program at the same time, as you could actually end up writing over what you are looking for or make the list of recoverable files incorrect?
I could see a function where it monitors where files are that have just been deleted, just in case you empty the recycle bin and realize you needed something from it. That way it would not take so long to find it, and the list would probably not be as long. It could also prove usually for securely deleting files, by showing the most recently deleted right there. I have a feeling a feature like that would be considered bloat by others here at the forum, so it will never be added. Plus it may also be a little demanding in resources, so not necessarily a good idea.

No, that would assume that you have only 2 drives and have no idea what you are doing. It's up to the user to know how to restore something and to where. The entire time Recuva is running and not allowing you to minimize to the system tray you can still use your computer to do anything... it just forces you to look at it and not be able to make it go away or make it stop wasting the taskbar space.

Minizmie to systray is a good feature and there are close to no programs I can think of that should not allow for it, *optionally* of course.

Please understand I honestly would like clarification on this, I do not wish to be ignorant, how is having two drives or not knowing what you are doing going to impact if a file is written over? In fact, I really just cannot quite grasp the two drives, I would think that with two drives you are less likely to overwrite as there is more space to be written to. Please, I am not trying to contradict you, I genuinely want to know and correct my understanding.
