Basically almost all the websites i try to download the same thing happens....i
will see like 2.5GB at a point when still copying and when i wake up i see 1GB
download, the websites downloads and start deleting some files.

Even sometimes when i close HTTRACK when i noticed it starts to delete files
then even the files still get deleted, this is really annoying. I mean i am
sure you will notice this too if at all you use HTTACK to download websites
for offline viewing. Its a really big problem.
