Compare Advance is a very easy to use folder compare, synchronize and backup utility.
Compare any two folders from the local hard drive, removable media (CD, DVD’s) or over the network, and easily see the differences between them. Unique views, folder coloring, summary node and highlighting features make picking up all the differences quick and easy. Then copy or delete files as necessary to resolve the differences.
Synchronize files between your desktop and laptop computers. First compare the desired folders from each computer and then resolve the differences with the advanced synchronization dialog, which makes it easy to see what each action will involve.
Backup your important files and folders to the destination of your choice, uncompressed or as a zip archive file. A detailed log report records which files have been copied, from where to where, and notifies you if any errors have occurred.
Advance. Compare Advance introduces a new feature called “Archive Folder Filtering”, which in some cases can save you many megabytes of space. So you don’t  need to backup folders which are simply extracted archive files.
