Using space sniffer hiberfil.sys comes up at 4gb per partition of my triple boot system (win 8.1 x86, win xp and win 8.1 x64). I dont hibernate and it is off in settings or says "never" so why do I have a hibernate file? Also AppData seems to be large at 5 gb anything in there to delete? My Win 8.1 x86 partition is consuming 97 gb of 133. I need to trim some files.
