'ncftp' on the same system downloaded it just fine, however. Lynx also reported an unknown file size when it transferred. The file size is 3.03 GB and other clients report it correctly - with the exception of browsers that seem to not be able to download it, either reporting it as nothing or a negative number.

lynx doesn't (yet) support large files (sizes bigger than 2^31 are likely
to be a problem).  As you note, not all browsers support large files.

There's a Redhat bug-report about this; so I had it in my to-do list
(which is very long ;-)

I'm guessing that Lynx sees the integer, interprets it as "negative," and ignores it. I have no clue in reality, however, because IANAP, and have no clue where to even *begin* to try to figure out what's wrong with this situation.

The system is Linux 2.6.10, using the ext3 file system. As far as I can gather from reading the size limit is 2 terabytes, however I only tested with 'dd' up to 7 GB.

Some applications don't bother keeping track of the filesize - those work
without many changes. Others have to be modified to use a larger data type
to store the size, e.g., to know when to stop reading.
