You will no doubt want to back up your game files, and should do so regularly during your game development. But which files should you back up?

When taking a backup, make sure you copy ALL the files listed below:

• GAME.AGF - this is the main data file for your game and contains almost all of the game settings. Without it, your game is lost.
• ACSPRSET.SPR - this is your game's sprite file, containing all the sprites from the sprite manager.
• ROOM*.CRM - all the ROOM*.CRM files are your room files, and obviously without one of them you wouldn't be able to go into that room any longer.
• *.ASC, *.ASH - these are your script files, and contain all of your scripting handywork.
• *.TRS - translation source files. They contain any translations that you've had done.
• AGSFNT*.TTF, AGSFNT*.WFN - these files contain any fonts you have imported.

Also remember to back up any sound, music and video files you are using.
