That is one hell of a messy C drive. Most of that shit can go.
That is one hell of a messy E drive. Most of that shit can go.
You may be best to redo the whole machine. It isn't healthy running that many potentially conflicting folders and files but it is up to you. You may be best FTPing what you want off the Xbox to your PC's Hard drive and building the Xbox HDD with an install disc like HeXEn or Slayers and then FTPing your stuff back on where you want it. The whole system needs a good flush out and a lot of that stuff you have on there simply isn't needed these day. Apps like dvdx_v2, Ejecttray, Loadtray, MediaXMenu, video_select_v2, XBMP are all well past there day and a lot of others there, you will probably never use and if you ever do, you just FTP them over when or if you ever need them. I suppose what I am trying to say is simplicity is best. keep it tidy and reliability will follow. What an install disc will do is get the machine to a running state by itself and from there you add what you want where you want it. What you have at present is a machine built about a decade ago using methods that were required a decade ago. Since then a lot of them have been incorporated into other apps and therefore made the basic original apps redundant.
Just to give you some idea. I run modchip machines and have 8 files in my C drive. You have 23.
And in my E Apps I have 4 folders. You have 20. See what I mean?. Maybe you like all the stuff in the machine, some people do. Personally I prefer it keeping it clutter free. I just can't see the sense of filling it with crap that I'm likely never to use.
