I just got a transfer cable for my xbox 360. Why does my mw2 gamesave come up as safari doent in xplorer360?

I go into my profile then go through all of the right sub-folders and the correct game save is there. However, when i mod it with modio then follow all of the steps, the mods do not work in campaign or special ops. Also, instead of saying that it is a SVG File, it says File Type, Safari Doent. Please help.
