This type of image format is similar to Adobe's PSD format in that they can both store images, lines, text, and layers. Adobe PhotoDeluxe was discontinued in 2002 and replaced with Adobe Photoshop Elements. However, as you'll see below, Photoshop Elements isn't the only program that can open and edit PDD files. PDD files that aren't image files are probably Medtronic Programmer Data files, which store patient information from a Medtronic Chronicle Implantable Hemodynamic Monitor. However, they might instead be Process Deployment Descriptor files used with ActiveVOS or Process Deed files. PDD is also short for terms that have nothing to do with the file formats described on this page, such as process driven development, professional disc for data, physical device driver, platform-dependent driver, and project definition document. How to Open a PDD File PDD files can, of course, be opened and edited with Adobe PhotoDeluxe, but chances are you don't have that program installed (and Adobe only has updates available for it). To open the PDD file for free, you can use XnView. This program is just a multimedia viewer and converter, though, not an image editor. Some other ways you can open and edit PDD files is with Adobe's Photoshop, Photoshop Elements, Illustrator, and InDesign software. ACD Systems Canvas supports the PDD format, too. Medtronic Chronicle software can open PDD files that are Medtronic Programmer Data files but we haven't been able to find a specific download link for it. If you're using a PDD file that works with ActiveVOS, see their ActiveVOS tutorial for more information on what the file is used for and how it works with the software. PDD files are required before you can make a similar file type used by that platform, called a Business Process Archive file (.BPR). Process Deed files work with Carlson software and hold deed descriptions from polylines, like the name and coordinates. A tool called Process Deed File, accessible through Survey > Polyline Tools, can open this kind of PDD file to edit its information and generate reports. Since this file format might just be a text file with the .PDD file extension, you can probably also open it with a text editor like Notepad++. If you find that an application on your PC does try to open the PDD file but it's the wrong application or you'd rather have another installed program open PDD files, follow this guide to make that change in Windows. How to Convert a PDD File The easiest way to convert a PDD file to JPG, BMP, TIFF, PNG, PDF or a similar image format, is to upload the file to CoolUtils.com. Once the PDD file is on that website, you can choose which format to convert it to. You have to download the converted file back to your computer before you can use it. If after you convert the Adobe PhotoDeluxe Image file, you want it to be a different image format that's not supported by CoolUtils.com, you can use a free image converter. Just convert the PDD to JPG or some other format first, and then run it through an image converter. Still Can't Open the File? If these programs aren't opening your file, you might not be working with any of the formats mentioned above, which can happen if you've misread the file extension. Some files share similar-looking extension letters/numbers even when they aren't at all related. Some examples include ADP, PD (Spore Audio Playback) PDF, PDI, XPD, DDL, IDX, PPD (PostScript Printer Description), PDB, and WPD files.
