Where does Rei's Minimap store your waypoints?

In what file does Rei's Minimap store its waypoint data?

I recently updated a server's modpack (from FTB Beta to Direwolf20's pack) and the waypoints disappeared in the process. I've combed through the folders of the backup from before I did the update and I can't find anything that looks remotely like storage for the waypoints. My objective is to, if possible, import everyone's waypoint data into the updated server setup.

Solution 1:

First off, they're stored client-side, so you can't restore players' waypoints on your side. They're in mods/rei_minimap in the minecraft folder. You should have a bunch of .points files in there.

Each file stores the waypoints for a single dimension in a world. Multiplayer waypoints are stored by server address, so if your server is on a consumer machine with a dynamic IP address, you should set up a hostname for it so players don't keep losing their waypoints.

Solution 2:

They are stored in the .minecraft\mods\rei_minimap using the .points extension, with a separate file for each map/server and dimension (including Mystcraft ones).

The format is [Map/save].DIM[#].points
