.XDP File Extension
File TypeXML Data Package
What is an XDP file?
XML file created in the XML Data Package format, a file format developed by Adobe Systems for packaging PDF data into XML files; contains the entire PDF document contents including form and template data; may also include character-encoded sections for binary content.
The XDP format allows a PDF file to be transformed to XML and back to a PDF without losing information. It also enables any XML program to read the PDF data.
XDP files are supported by Adobe Reader, Adobe Acrobat, Adobe LiveCycle, and other Adobe programs.
