ZSKSoft Synchronizer

ZSync is a multifunctional directory synchronizer. Thanks to the universal approach, it is equally convenient to use for synchronization with a laptop, backup, FTP site publishing, anti-virus database updates, synchronization with a remote computer, searching for differences between two folders, and much more.
Unlike other synchronizers, which simply compare which of the two files is newer, ZSync can remember the synchronized state, and track the changes in each directory separately. Thanks to this, it works much more accurately, detects suspicious changes and prevents conflicts (when the same file changes immediately in two places).
Working with the program is easy and convenient. A single glance at the screen is enough to immediately see the general state, what has changed, how serious it is, and what is proposed to be done. Levels of severity (changed, suspiciously changed, conflict, etc.) are highlighted in color, the status of files and folders is indicated by easily recognizable icons, and right there, where you plan to perform some operations, the corresponding buttons appear. If some files and folders do not need to be synchronized, they are simply transferred to the "ignore " category by the mouse.
Especially bright all the best qualities of ZSync appear when synchronizing with a remote computer (for example, a home computer with an office computer). To do this, you can use any suitable media: email, flash memory, and even regular diskettes. The inevitable pads (the letter did not reach, the diskette was not read, etc.) do not cause failures, but only make ZSync tense up and take the necessary measures to ensure that the results of your work are not lost.
