HS check [Type: Question]

[zonalimitatore]

When the handshake is captured, who can tell me that is complete? I mean, there is a "way" to check if the .cap file captured it's 100% ok and the program can work on it?
Or, if the program has put it into "handshake folder", it means that it's already good?

PS. I've noticed that, if I capture multiple handshake of the same AP, I've no multiple files, but just the single one.
It's the most recent or the program keep saved the first one?
