When we use Dropbox, with large files, synchronization between the client and server is quite slow. Dropbox now supports storage on server without synchronization on client, i.e. we can choose which files/folders to be synchronized.
First right click icon dropbox in system tray, select click `Preferences…`
Then, select ` Advanced` and click button `Selective Sync…`
Then, uncheck those folders that you don’t want to sync to client and click button `Update` to finish.
Hope that helps!
