The data in chat server is always stored at <123 Flash Chat install directory>/server/data/<group name>/ in terms of group.
The contents are categorized as:
logs/access.log (general access log)
manager.log (admin panel log)
error.log (chat error log)

If the client chooses the user system by default, the information on all users will be stored at members/.
If the file is based on binary system, one file stands for one user and the file's name is the user's name.

All the information in the room is stored at rooms/ with room id as the file's name.

All the settings information, such as friend list, font size and so on, are stored at userinfo/.

All the information on chat is stored at online.txt/, such as connections|logon_users|room_numbers.
For example, 1|1|10 stands for one connection, one logon user and ten rooms in the chat.

For room_*.txt, * stands for room id, with online user list in room id stored in the form of jack and tom.

What we should integrate is basically the content in online.txt and room_*.txt.
