MultiSH3 is a utility that will change the folder name in My Documents that Silent Hunter 3 uses to save campaign and career information. It does this by patching a file in the game's root folder called FileManager.dll. Stock SH3 is hard-coded to save this information in a folder called My Documents\SH3, but given the large number of supermods and other mods it may be desirable to be able to separate careers by saving them in different folders. For example, you might want to have a stock SH3 1.4b installation, a TGW installation and an NYGM installation, each with their own career information.
The obvious benefit of this is that it prevents any possible confusion over which campaigns and careers belong to which installation. Mod developers may find it useful to have a known safe copy of SH3 and one or more development copies, each completely separate. Gamers may find it useful to be able to remove, repair or update supermods without having to uninstall the lot and start again (anyone who has needed to modify their Grey Wolves installation should see the benefit of this immediately).
It is available for download from

Jaesen Jones has made a maintenance release of SH3 Commander that is compatible with MultiSH3. To run them together you will need SH3 Commander 2.6.1.124 or later.
