cache the value. don't call Qopen directly in the engine. instead call QFS_Open (generic) or QFS_WOpen (write only, zip flag). rework QFS_NextFilename to use a dstring (avoiding a potential buffer overflow), support 10000 files and work from the top-level fs_userpath directory. adjust QFS_WriteFile and QFS_WriteBuffers etc to suit. make sw32 screenshots actually get written. hopefully everything gets written to the right places :)
