- Synchronization Steve's suggestion to use a file synchronization tool is a good idea for now. Of course such a tool has limitations, it cannot resolve conflicts, this means you will loose the file with older modification time, even if this file has changed. With other words, you cannot do changes on both file system, only on one. Only a specialized tool can resolve the conflicts, hence to have such a tool would be a fine thing. Unfortunately the effort for developing such a tool is high, because resolving conflicts cannot be done without user interactions - an automatic resolving is impossible if a game has changed in both databases - I guess the development time between four and six months (I took also into account that an additional database file is required for the change history). Such a tool is far future.
