DirectorySync is a directory synchronizing and backup utility providing automated, real-time syncing and scheduled, configurable backups at an affordable price. It differs from other directory and file syncing utilities in that it actually senses changes in real time, as you save your work, and quickly synchronizes only the changed/new files and directories with an external drive, a memory stick or a shared directory on a server, ensuring incredibly fast and efficient performance.
Sync your folders and directories with up to 2 other directories, it's like saving your work in 3 places rather than 1 and it all happens automatically, no scheduling is needed, DirectorySync senses your changes and syncs your changes in the background in real time.
You can also backup your directories in compressed format to save space. Backups are configurable with scheduling options and more.
