SyncFolders helps you to synchronize the contents of two folders, including any subfolders. The folders may be on different disk drives, on the network, or storage devices attached to the USB port, including external hard disk drives, flash drives, and any other type of USB storage device. The program allows you to easily copy new and updated files and folders in either or both directions. SyncFolders is a very useful tool for backup and synchronization purposes. Key features: Supports two-way synchronization of files and folders. Can easily be used as backup tool. Shows a preview before the actual synchronization takes place. You can override actions if desired. Detects conflicts or file collisions when a file has changed in both locations since the last sync operation. Therefore, SyncFolders tracks file modifications and deletions in a local database. Propagates deletions and detects file renames. Default actions can be defined in case of synchronization conflicts. Integrates with Windows' Task Scheduler to support scheduled synchronizations. Supports file and folder filters. Can handle long file names and files of any size. Supports multiple synchronization rules in a single rules file. Deleted or overwritten files can be moved to the recycle bin or to a time-stamped history folder. History files can be deleted after a user-defined period. Unlimited number of files. Can ignore one-hour timestamp differences caused by DST switch for synchronization to FAT file systems. Easy-to-use.
