I am an ordinary user, not having much knowledge of HTTRACK. I recently
downloaded a portal through HTTRACK. Most of the advance features is beyond my
understanding.

I want to know what is the method of testing that a portal has been fully
downloaded, and nothing is missing.

Secondly, i found some of the files missing. Now i want to update(recover)
those files. I dont want to go through the lengthy downloading process again.
Without interfering the all downloaded files, what is the method to recover
the missing files.

Please help.
