improvement for dropbox data storage

At present, the directory structure at dropbox is root > Apps > SenSee > Experiment_Name, which could be an annoyance. Here is why. If a single dropbox user runs the app on more than one device, both devices would push the data to the same directory, for instance, if device 1 has an experiment with directory "exp0004" and device 2 also has an experiment with directory "exp0004", then data collected from both experiments on the two devices would be pushed to the same directory in the user's dropbox. It appears that dropbox would not overwrite the files with same name, but append (1), (2) etc to file names -- there is no data loss, but an annoyance.

There are two possible solutions I can think of right now,

• making directories on all devices unique, perhaps, using certain UUID as part of directory name
• creating subdirectories for each device at dropbox server.
