XAM - Storage content in "directory like" structure

Hi,

Is it possible to store binary content in Centera (using XAM) in a "directory like" structure ?

Example:

If I want to store file by month, is it possible to store them all under "/2009/11/" , maybe using a field property for all xset?

Then, can all these file (in "/2009/11"can be delete at once ? Maybe, they can be individually delete using a XAM query on the field used to store "/2209/11" and the delete each results seperately ?

Thanks,

David.
