What is an AGMODULE file?

An .AGMODULE file is an Adobe Photoshop Lightroom Module file.

Adobe Photoshop Lightroom Module files (extension .agmodule) are modules used by Adobe Lightroom to add or define specific functionality within the app. These files usually provide layouts, templates, or custom output features such as the Book module, Web Gallery module, or template toolkits.

These module files are developed by Adobe Systems Incorporated as part of Lightroom. They are stored in Lightroom's Plugins folder (or within its built-in module mechanisms) and are treated similarly to .lrmodule files. Users installing or updating Lightroom may obtain .agmodule files when installing additional templates or when Lightroom updates its built-in output/layout modules.

Internally, .agmodule files contain compiled scripts and resources - for example, Adobe compiles Lua scripts (rather than distributing them as editable text) for at least layout-toolkit modules. Modules include template files, resources for book layout (such as guides, text frame definitions, and photo cell layouts), and possibly binary components. For example, custom page templates under layout_toolkit.agmodule include Lua byte-code scripts that define layout behaviors.
