Is anyone familiar with a program that will sync only SPECIFIC folders on my computer to a specified location on my external hard drive? In other words, I want it to duplicate the folder on the external hard drive and update it to match the contents of the folder on the computer when applicable. I have been doing manual transfers for a long time now but it's not as simple as copying over the folder and telling it to merge the folders and skipping the duplicates. Sometimes I decide to delete files or move them to different folders within the folder; therefore, simply copying the folder over does not work. I refuse to use Windows File History because I cannot detail specifics and I cannot track its progress. What are some of the best software out there for creating backups and syncing files between your computer and external hard drives?
