FYI, CuteFTP Pro and Server support a propietary command for multi-part
uploads (COMBine). The help file details how COMB works. It would be nice if
more clients and servers supported this command. The other propietary
command they support is XCRC, which does a checksum on transfers or prior to
transfer to determine whether overwrite or resume should be used. Yeah I
know, its not in any RFC. Wish I had time to propose these and other
commands to the working group...*sigh*. I'm interested in your p2p stuff,
possibly for support in Pro 3  as I've had some thoughts on that in the past
(CuteMX was also my baby). Do you plan to keep it open, as we have done with
COMB and XCRC?

Hello,

In our application (Fastream FTP++ P2P) we have multiple connection
downloads (similar to Download Accelerator/GoZilla) with the help of REST
command. I simply divide the file into segments and then merge the
downloaded parts on the local-side.

I want to implement the same feature for remote part also. I mean multiple
connection uploads. However, on the remote size, there is nothing like a
merge command. There is the command APPE but it only appends a local file to
a remote file. Wouldn't it be nice if we add such a command to FTP?

Also, in our application, we have a command called SITE MD5 similar to ones
found in UNIX systems. But in our case, the MD5's are cached with a
background thread. This enables KaZaA/iMesh like P2P functionality with
multiple source-IP/port downloads. However lack of support from other
applications limit the use to within FTP++-to-FTP++ only. As you may have
understood, I propose this command also.

Best Regards,

G. Ates
