Sync Center manages the synchronisation of files between a computer and a server. Synchronisation is used in order to access files normally held on a server when you are away from the location where the server is held.
The way this works is to hold a copy of required folders on your computer. This is usually synchronised when you log on, log off the computer whilst you are in the office. Also, if the computer is idle for a period of time (usually 15 minutes) then a synchronisation will take place.
From time to time, you need to check the results in Sync Center to resolve any issues found. These issues include changing a file on more than one computer between synchronisations, a file being deleted on one computer but not the other etc.
Start Sync Center by double-clicking on the Sync Center icon in the taskbar.
The list above shows some synchronisation errors. Most of these are showing that a file created on the laptop whilst offline has the same name as a file already on the server. To resolve the issue, right-click the file (or group of files) and choose an option. Usually this option will be to keep one file over the other, or to keep both files (if you are unsure).
Note that sometimes Sync Center will report some strange issues; it seems to take a pessimistic view of what has changed.
I have also found issues where folders are not synchronising. I don't think there is a particular reason for this other than a bug in Windows. Although it may be that because this folder begins with a space character, this may be the problem.
if you look at the above screenshot you will see the topmost folder has not synchronised. Look under the heading "Offline availability".
