78 /** \page fs File System
80 All of Quake's data access is through a hierchal file system, but the contents
81 of the file system can be transparently merged from several sources.
83 The "base directory" is the path to the directory holding the quake.exe and
84 all game directories. The sys_* files pass this to host_init in
85 quakeparms_t->basedir. This can be overridden with the "-basedir" command
86 line parm to allow code debugging in a different directory. The base
87 directory is only used during filesystem initialization.
89 The "game directory" is the first tree on the search path and directory that
90 all generated files (savegames, screenshots, demos, config files) will be
91 saved to. This can be overridden with the "-game" command line parameter.
92 The game directory can never be changed while quake is executing. This is a
93 precaution against having a malicious server instruct clients to write files
94 over areas they shouldn't.
