Moving existing edocman to a category based folder structure

Hi

In the configuration, I see this option:

'Use Herachical Folder Structure'

Currently I have this turned 'off'.

If I turn it on, will it automagically create a folder structure under the edocman file root that matches my category structure, and then move existing files into the appropriate folder?

If not, is there an easy way (eg without re-uploading) to move from a 'flat' storage model to a 'category' storage model?

I want to use the google drive integration, and it does not make any sense with a flat structure.

Cheers

Nigel
