How do I exclude unnecessary file formats like .dll, .exe. .ttf, .mui, .cur, .etc which can be easily replaced with reinstallations of programs in reformated or new hard disks. I am not fussy with some unnecessary files that got backed up anyway, because I know I cant microchoose every file in my giga harddisk. I tried to exclude files by typing " *.dll , *.exe, *.ttf, etc " but couldnt with your Windows LIve One Care software. It looks like I have to choose every one of them and go back and forth thousands of times if not millions of times to get my backup done as I like it to be done. Have you ever heard of time management if not anger management?? I dont bother to choose folders or files to backup, I just back up the whole C: drive and am trying to exclude general file formats above and be done with it in less than 5 minutes so I can go on with my life. Do you understand what I am saying??
