ZSKSoft Synchronizer 2.2.1
"ZSKSoft Synchronizer (abbreviated as ZSync) is a multi-purpose folder synchronization program. Purchasing it, for instance, to synchronize with your laptop computer, you will be able to also use it for publishing your web site on the Internet, creating backup copies of a complex project, organizing teamwork with a colleague who you communicate with via e-mail or just for comparing two folders and much, much more.
Other synchronization programs merely compare contents of two folders to be synchronized and seek for the file with a newer date and time. ZSKSoft Synchronizer can do that too, but it can also remember the synchronized state and during the next session it looks for the actual changes only. Imagine you have edited a file on your laptop computer and then, having forgotten to synchronize, added more changes to the same file on your desktop computer. ZSync will make sure none of your work gets lost; it will detect the conflict, highlight the file in red, and will not synchronize until you take the required steps to resolve the version conflict.
A particular attention is to be paid to the ease and convenience of operation. Having started the program, you will instantly see what has changed, how serious that is, whether or not there are any conflicts or suspicious changes, and what is going to be done. Everything is intuitively clear: the files and folders state is marked with easily recognizable icons, gravity levels are highlighted in color, and right where the program is planning on taking some actions, it places the corresponding action buttons. To exclude files and subfolders that shouldn't be synchronized, just drag them, to the "off" category with your mouse. The special explanation pane provides detailed description of any file or subfolder: what it was like before, what it is like now, what seems to be suspicious, etc."
