A file with the XPD file extension may be a PlayStation Store PSP License file. They're used for DRM and are downloaded from the Sony PlayStation Store when downloading content. The XPD file is needed when putting files on a PSP.

If you have a different kind of XPD file, it's probably an XML Pipeline file, which is a web page created from an XML file. This transformation typically takes place via XSL or Extensible Stylesheet Language

An XPD file that's in neither of these formats may instead be a SkyRobo file or an XPD Cache file, which holds information about a 3D object.

How To Open an XPD File

PlayStation Store License files aren't intended to be opened but are required when transferring DRM-protected files and games to PSP devices. Media Go is the program that uses them. See Sony's How to download PlayStation Store content to your PlayStation Portable document if you need help.

If the XPD file you're using is an XML Pipeline file, web browsers like Internet Explorer, Firefox, and Chrome will open the file. Text editors like Notepad++ should be able to open them for editing.

SkyRobo files can be opened with the programming application by the same name, but I can't find a download link for it.

Autodesk's Maya uses XPD files as XPD Cache files. They describe the location, geometry and other details about 3D objects used within Maya.

You can read more about this particular format on the Autodesk website, here and here.

Note: If none of these programs are able to use your XPD file, double-check that you're reading the file extension correctly. It may actually be an XPI or an XP3 file, both of which share common letters with the .XPD extension but of course open with different programs.

If you find that an application on your PC does try to open the XPD file but it's the wrong application or if you would rather have another installed program open XPD files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an XPD File

Most files can be converted using a free file converter, but I don't think that's the case for any of the formats here that use the XPD file extension.

PlayStation Store License files most definitely need to remain in their existing format. Changing the file extension to something else or modifying anything in the file wouldn't be a good idea because then Media Go wouldn't know what to do with the file, and the content likely wouldn't be delivered to the PSP properly.

Since XML Pipeline files are XML-based text files, they can probably be converted to HTML, TXT, XML, and other similar formats using a text editor like Notepad++

If you have SkyRobo already on your computer, or if you know where to download the program, you may try using it to convert the XPD file to some other format. Most programs that support saving or converting files to new formats have the option in the File > Save As menu or in an Export or Convert menu.

I don't suppose that XPD files used within Autodesk's Maya program can be converted to another format, but just like with SkyRobo, you may be able to do it through Maya's File menu.
