[icq-devel] About oscar file transfer

[Christophe Minguet]

In previous versions of icq (before V4) full file transfer process was made
using DC.
In V4 file transfer is initiated by SNAC 4,7 messages (description of files,
response of remote user) and then the file sent by direct connect.

As i told in a previously, you will find more information about the protocol
there :

Good luck
