What is an UPD file?

UPD files have multiple uses, and Program Update Document is one of them. Read more about the other uses further down the page.

Program Update Document

Files that contain the .upd file extension are typically associated with software update files. The UPD files used for updates contain text information about the contents of an associated program update.

These UPD files are similar to the README files included with many program downloads, but UPD files are included with the updates and not with the download of the actual application itself.
