I do not use IE; i *RIPPED* it out by its guts from Win98SE and as much as possible (but impossible to completely) in Win2K. 

Good, very sensible!  I see that you are using Netscape 7.2.  Dare I
presume that you are using Netscape 7.2 for downloading files off of
the web?

I had a lot of trouble with Netscape saying that it had downloaded the
complete file, only to find that it had actually quit after being only
part of the way done.


It is IE that has the real reputation for doing exactly that (although Netscape might do it too).

For FTP downloads, I use ProZilla, which unfortunately for you, only
runs under linux, and other unix like operating systems... but what
I describe will give you an idea of what is possible:

ProZilla goes out to the ftp site, and starts up to 4 different requests
for the file.  The first asks for the first quarter, the second, the second
quarter, the third, the third quarter, and the fourth, the fourth quarter,
and it merrily sucks all four quarters of the file from the site at one
time.  It won't quit until you stop it, or it has successfully downloaded
the entire file.


Sounds much like many other download managers. I find Free Download Manager http://www.freedownloadmanager.org/ a pretty good solution for windows.

The server side has no say in whether or not you can resume a download. It
is entirely up to your download manager... and as I said, even the one
in Mozilla, and Firefox is not very good. The one in Netscape seems to be
even worse. The transaction that goes on during a file download is one where
your manager passes the number of the block it wants to the server, and the
server sends the block. Your download manager could ask for the blocks in the
reverse order, or random order if it wanted to. The server side would neither
know, nor care.


That's not actually true. Almost all ftp servers will support resumed download by default, but it can be disabled and some older servers do not support it by default. However, these days it is very rare to find an ftp server that does not support resume (although many will limit the simultaneous connections to a single IP address). Similarly, http servers do not necessarily support resume - although most do, there is still a substantial proportion that do not.

Still, using a decent download manager is strongly recommended.


Try googling the following words: "download" "manager" "windows"

It should get you a whole pile of download managers that will work under
netscrape on windoze.

One other thing I would suggest you do, is abandon netscape, and download
mozilla suite 1.7 from http://www.mozilla.org

It is a much better implementation than the ad ridden mess that netscape
became after being bought by AOL.


You should then abandon the mozilla suite, and download firefox (and thunderbird for mail, if you want to switch mail client too). The mozilla suite itself is pretty much dead-end - all its developers are concentrating on firefox. Opera is another solid choice, if you like its style.
