If I pick this on a folder, does it leave the original files alone and simply make a synced backup copy in the dropbox folder? This is my desired result, but in searching I see a lot of irate people who have their files moved away or something. Perhaps that is something different though...
Also, what is the general thinking on the fact that with continuous sync, if you accidentally delete or otherwise screw up some files or directories, it will sync with the cloud and everyone else? Is the versioning in dropbox good enough that this is not a concern? It's tempting to just do periodic manual copies when everything is in a known good state.
