The HTTrack 32-bit version 4Gb file size boundary bug is even more severe then
I initially thought.

When a big zip file (with a file size over 32-bit 4Gb boundary) is being
downloaded the first time (using action "Download web site(s)") and then is
Skipped (by pressing the Action "Skip" button) at the time when the downloaded
zip file part has just passed the 32-bit 4Gb file size boundary then when the
same HTTrack project is restarted using "* Update existing download" (which
HTTrack automatically does because it knows the zip file hasn't been fully
downloaded yet) then a very nasty bug happens.

Instead of downloading the remaining last part of the zip file (the part
beyond the 32-bit 4Gb boundary) and appending this last part to the partly
downloaded zip file (having a file size just over the 32-bit 4Gb boundary) on
the local disk the whole zip file is being downloaded anew (from the very
first byte again as explained in my previous post) and here comes the nasty
bit, the partly downloaded zip file on the local disk (which still has a file
size just over the 32-bit 4Gb boundary) still increases in size resulting in a
total corrupted zip file download. If I would let the download finish then the
downloaded zip file on the local disk would be twice as big (reaching over 2
times 32-bit or over 8Gb !!!) compared to the original zip file on the web
site.

I have performed many tests to rule out any mistakes on my end but seriously,
HTTrack 32-bit version has very nasty bugs when downloading large files which
passes the 32-bit 4Gb file size boundary.

I would like to know from the HTTrack maintainers or developers if this nasty
32-bit bug will be resolved in a updated HTTrack release (the last release
dates back from 2017).

Hope to get some feedback regarding this bug.

Thank you.

With kind regards.
