In the past I have described how to make Dropbox work with Thunar for XFCE users, now I am going to see If I can achieve the same goal for KDE. Dropbox is a great utility which remotely stores documents and other files, and can sync them across multiple computers over the Internet. what I did was to follow the instructions provided by Dread Knight. Afterwards, I figured out that this method could be used for any Linux desktop environment or windows manager and is preferable to the Thunar method mentioned above. If you need, create a Dropbox account here
