I am trying to back up my hard disk to an external hard disk using SyncBackFree program. When choosing what to back up, it makes me choose a folder. All of my files are in subfolders of folders that are part of Libraries which are not acceptable. Is it possible to change a library to a folder or do I have to move all my files and folders into 1 new folder. Otherwise, can anyone tell me of a simple, free backup program that is only good for 30 days. All of this is to get ready to download Windows 10. I'm not even sure that is a good idea. Comments?
