Hi guys, Just went to plug in my external HDD to back up, and Time Machine tells me that there is 118GB of files to back up. I've just installed iLife '11 and iWork '09 and upgraded to 10.6.6, but this seemed a little outrageous, and after a quick Finder search of all files modified since my last backup (10 days ago) I discovered over 10,000 (that's all Finder can tell me, I assume that there is more) .apversion and .apmaster files, and folders like "ct2UqWF2Tn28m2XMi6r46A" all in various iPhoto directories, created at the time I would have installed iPhoto. Is there some way I can get rid of these? Because besides taking up space on my ext HD and taking ages to backup, they seem to be taking up considerable space on my internal drive as well. Or do I have this completely wrong and those files aren't taking up space and I am just missing something? Thanks all, Michael.
