Some questions from a newby.

I recently lost some E-Mail files/folders, call them what you will and went onto the Web to look for recommendations for an appropriate software and Recuva came up and I installed it.

I did a scan and the results showed:

Found 1,896 files and I'm in the process of recovering them.

However, under Found it said, 291,751 ignored so could anyone explain what that means.

I then noticed some words. Lost license key. Could anyone tell me what that means?

I've never seen Lost License Key, in relation to Recuva. Where does that message appear?
