File type: Various data file
The pdom file extension is used by Eclipse for its index database. A pdom file contains indexed data about a programming project.
The file is created and maintained by Eclipse's development tools to support project navigation and code-related features.

The pdom file extension is associated with Eclipse, an integrated development environment for Microsoft Windows, Apple macOS (Mac OS X) and Linux.
A pdom file stores indexed information about a programming project. Eclipse uses this database to keep information gathered from project source files and other resources, allowing its development tools to provide features such as code navigation and lookup.
The database is an internal part of an Eclipse workspace, rather than a document intended for direct editing. Eclipse creates and updates it as the project is indexed.
Open a pdom file through the Eclipse installation and workspace that created it. Eclipse uses the file internally, and it is not intended to be opened as a standalone document in a text editor or another general-purpose application.
On Microsoft Windows, macOS and Linux, Eclipse may rebuild the index if the associated project is imported into a workspace and the index is missing or out of date.
A pdom file is an internal Eclipse index database and does not have a useful standalone conversion format. It is not normally exported or converted with a separate utility.
To reproduce its contents, open or import the associated project in Eclipse and allow the development tools to rebuild the index.
