I'm confused. The pc was not shut down but my kid must've done something to
HTTrack so I 'resumed' my download.

It was about about 4G when it stopped or whatever. When I resumed, it was 3.3G
but I quickly went to about 4G and then it declares that mirroring is
finished.

I don't think it has really finished at all. I checked into one of the folders
and found partially downloaded videos.

I'm confused as to how HTTrack works. Should I have chosen 'update' instead of
'resume'?
What do I do now? 'Update' right (to complete the mirroring properly)?
