PTPdrive integrates a digital camera operating in PTP/MTP mode into the Windows by mapping it to a local drive letter. Pictures can be accessed by simply opening them from a drive letter - there is no need to run a separate application to transfer the pictures anymore. PTPdrive enables any Windows application to access the pictures in the camera. PTPdrive can work with any PTP/MTP digital camera, as long as the camera is visible in the Windows Explorer, eg. Nikon D90, Canon Rebel XSi, and many more.
