Synchronize files and folders between locations.
SyncToy is an application that synchronizes files and folders between locations. Typical uses include sharing files, such as photos, with other computers and creating backup copies of files and folders. It is an easy to use, highly customizable program that helps users to do the heavy lifting involved with the copying, moving, and synchronization of different directories. SyncToy can manage multiple sets of folders at the same time; it can combine files from two folders in one case, and mimic renames and deletes in another case. SyncToy actually keeps track of renames to files and will make sure those changes get carried over to the synchronized folder
