Hey, thank you very much for that fast and good support.

So, these tmp files are just created as tokens in the beginning of the update
process only for save the information which files are yet not finished and
have to be recopied at the end of the process. Is that right? (Seems at least
to work like this...)
I really would enjoy a possibility to let these tmp first/only reupdate.

Because the main problem I've left now is:
HTTrack overcopies every (still finished) data file (like zip, pdf etc.) when
I run it by 

httrack.exe "www....com/.../" -O "D:/websave/" -i -A0 -v -%v -%I -X0  
--display -%c1

I don't understand why!
After all HTTrack DOES know which files are different (corrupt) - because for
these it creates the tmp-files !?! ... and only these files should be
recopied.

Thanks for your help!
