Files that contain the .pdd file extension are most commonly associated with the Adobe PhotoDeluxe image-editing software application. The .pdd file extension is given to the images that are created with this software program.
PDD files are compressed image files. The PDD file format allows for added space on the user's hard drive.
While Adobe PhotoDeluxe was the software to primarily use the PDD file format, that particular application was replaced with Adobe's Photoshop Elements in 2002.
The Medtronic Programmer software also uses the .pdd file suffix. These PDD files contain data files that are referenced by the Medtronic Programmer application.
