[Box Backup] Problem with 'get' command on large files

[Nick Knight]

Yes I forgot to mention the bug I found was on the server - so in this
instance generic to box not just to windows.

There should be nothing special to configure large files. autoconf as =20
you say takes care of it.

You're compiling on 64bit linux, I don't think it's possible to not =20
have large file support. Your config.log says it is enabled.

Sounds suspiciously like a bug Nick had found in the windows version. =20
He did say he thought large file support didn't work on any platform - =20
oops!

I have no experience of it myself, unfortunately I can't afford to =20
back up my large files, too many small files that are more important. :)

Still, I also use 64bit linux so I'll give it a go when I get chance.

Cheers,

Martin.
