Have you read the help file? you should get Synchronization Complete after you run it. You need to have two folders with a identical names. I have a folder on my D drive called Sync folder and another on my external drive with the same name. I have all my documents and folders in the sync folder on the D drive and I sync this with the same folder on the external drive.
You need to select a Source folder and a Target folder in my case it would be D:\Sync Folder ------> F:\Sync Folder
In Synchronization Setting you need to select from the following options:
A description of what these do is given in the settings dialog
After setting up the required options you need to select the Compare button on the left hand side and this will compare the two folders and inform you of any changes, after that you need to select the Synchronize button on the right hand side, this will then sync the folders and give you confirmation that the operation is complete.
Hope this helps
