bot requires .pwf only, the rest is calculated.
.pvi (visibility table to throw grenades) is calcualted in the moment of adding bot to map, and when it is done it does not need recalculation. this is the CPU eating procedure (that's why gae lags on first map load if there is no .pvi)

.pxp is saved on map end when map changes (or all bot bot leave? not sure) and contains the experience gathered during a game - they will rember where on maps are danger spots - like places from where they were killed, so they will look more often there when closing to the specified wayopint. on next map load the bot also loads .pxp and behaves as if he played on map before. (if .pxp does not exist then first map play is a bit different, cause they learn). And they learn with each map play, if i rember well.

when you put new .pwf in place of allready existing file, it is suggested to delete old .pvi and .pxp files.
