I do a daily back-up of my 'My Documents' folder on a CD-RW to sync it with my home laptop, but as not all files are changed or new files created every day, a CD burning software that can automatically check the last modified date and check for new files, and then automatically burn only those files that need updating would be wonderful. Does anyone know of such a software? Thanks!
