A free program for people who, in addition to a desktop computer or laptop, use various storage devices, such as palmtops, external hard drives, cameras, cameras, mp3 players, pendrives, or simply additional desktop computers or laptops. This easy-to-use, simple tool is designed to relieve the user of the burden of constantly copying, transferring and synchronizing data between different directories, shares, devices and computers. The application provides a clear and functional synchronization manager for any device.

In order to ensure full control over the data, a register of changes is kept. Version 2.1 is based on Microsoft Sync Framework 2.0, which has enabled a significant acceleration of file copying operations. The program also handles file system errors better when copying, which is especially important when copying over the network.

In addition, the configuration is automatically backed up and a number of minor bugs have been fixed, including the problem with NAS drives, uploading files to the SharePoint site, deleting data in Echo synchronization mode and the user interface.
