While the application is syncing all of your files to your chosen folder it is also capable of keeping a log of all the actions that it takes while it processes the data if you tell it to.
To tell the app to keep a log of all the actions it takes in the synchronisation process just go to the Synchronisation Log tab page and tick the 'Log Sync Activity' checkbox.
You also have the choice to tell the application to keep a log of files that it finds to have equality while synchronising.
The final option is to specify a maximum age that the application will keep the log files for, all log files older than the specified 'Log Age' will be removed periodically by the app.
All of the log files will created will have the date and time stamp in the log file name. To view a log file you simply click in the 'Open' box next to the log file that you want to view and the log file will be opened in the XML log viewer.
