Is there a way to 'resume' a download by starting a mirroring process on an
existing folder structure?
I'm asking because I did half of a mirror job (5GB) but power went out. Then I
resumed the downloading, but I had to cancel it before it was done and
WinHTTrack deleted all the files saying "Purging" for every directory :/
I undeleted the files right away, but now when I continue my mirroring,
WinHTTrack is downloading and overwriting files which are already there. I
checked if they are corrupt, but the files are identical.

Any way to make HTTrack download only files which are not present in the
folder structure?
