Today it-s not a problem to find the program which would solve this or that computer problem. It is much more difficult to find the program which would solve this problem easily, quickly and effectively. For example, to carry out comparative analysis and file synchronization, enough powerful analytical means which would allow to get this or that file to compared folders by certain criteria is required. File Sync is a rather new means and folders compare program which consists of one window, has a simple interface and nevertheless approaches for the decision of all problems you face in such problems as comparative analysis and file synchronization very successfully. Pay attention that File Sync allows to carry out both procedures in certain sequence. That is for the first time the folders compare program should define what files concern to one of folders, and what ones do to both folders (that is to carry out the comparative analysis). And only then it is necessary to find out whether the compare folders program can be convenient for file synchronization and whether this synchronization is necessary to you. The first tool is started with the help of -Analyze-, the second one is done with the help of -Sync-. Pay attention that the program practically hasn-t got difficult and not clear for usual user commands and panels of tools. All basic for the user commands in the compare folders program located in the program window are Analyze, Sync, Stop (the command to stop processes), Browse (to load folders into a program window). Processes pass in the program very quickly. It-s also a consequence of program simplicity (which however does not stir its functionality). The work in the program is passed in the form of problems during which you carry out the comparative analysis and file synchronization with each of pairs of directories.
