Quick question for those of you who use the HyperDrive Colorspace UDMA for backup photo storage: In order to do just an incremental backup from a memory card (i.e. backing up only the new images on the card; not those previously backed up), is it necessary to have created & selected a new folder on the memory card for the new images? (I assume that without doing so the Colorspace cannot differentiate between previously-backed up images & the new images).

Thank you for your help.
