Export and import Grid, hot cues, scenes BUT NOT the music files themselves

I have all my Music in my Dropbox Folder, thus, in a Cloud. I did a lot of work for correcting grids, Scenes and Setting hot cues. I would like to save that work, but I don't want to move my Music files. I know that the grid, Scene, hot cue Information is stored somewhere on my C: drive. But I would rather like to have it in my dropbox as well (so all my editing is backed up automatically), or at least from time to time do a Manual Export to the dropbox Folder. I already did the latter by using "Export Collection in XML Format", but I have no clue, whether that worked. Most surprisingly, you can Export the Collection by doing so, but there is NO respective Import function… So why should I Export something, which I later on cannot Import????

The Point is: I want a reliable backup (and Import) of my grids, hot cues, Scenes but not of my Music files. How canI do that?

Thanks a lot in Advance!
