This is a guide to some of the resources in the data folder used by various Crossfire Clients.
If an image normally obtained from the server is found in this folder, it is displayed instead of the server version.
If you are designing new graphics for crossfire, you may draw the graphics and test them in game by placing them in this folder. It is not necessary to run a server to test the graphics.
For example, if the client needed to draw a dwarf, it might need to find a dwarf_p.111.png image file. Normally this file would be downloaded from the server, but the client looks for .crossfire/gfx/dwarf_p.111.png before it looks in the cache, and before it asks the server for the image.
