This section contains a list of files, not all of which are documented here, with brief information on who uses them. This is useful from time to time when digging through game directories sent with bug reports. Files marked [*] have descriptions here. Obvious names have usually been omitted (i.e. `echoview.ini'). This list is expected to grow.

"Standard" means that every nontrivial program handles this file. "PCC1" means PCC 1.x only, "PCC2" means PCC2 only, "PCC" means both versions. Likewise, "PHost4" means PHost 4.x only.

This list, like the rest of this documentation, shows file names in all-uppercase. See the introduction for a few words about file name case.
