I tried to find answer here but no luck so I will ask - risking that the answer is already available on some place I did not look into.

So question is: What actuality happens if Armory is used and wallet deleted from after use by pressing Delete/Remove Wallet button on the Wallet Properties screen?

Is wallet file on the disc deleted?
Can this deleted wallet file be somehow restored and keys recovered and bitcoins get stolen?

In essence the question is: is laptop or PC with Armory wallet previously DELETED as above, is stolen/lost?
Is it possible to recover bitcoins from it?
