An .lrdevplugin file is associated with Adobe Photoshop Lightroom and contains the code and supporting resources for a Lightroom plug-in. Plug-ins extend the application's functionality with additional features or integrations.
Adobe Photoshop Lightroom supports this plug-in format on Microsoft Windows and Apple macOS, formerly called Mac OS X. The package is used as part of Lightroom rather than as a standalone document or image file.
Open or install an .lrdevplugin file from Adobe Photoshop Lightroom's Plug-in Manager. In the manager, use the option to add a plug-in and select the plug-in package.
Adobe Photoshop Lightroom for Microsoft Windows and Adobe Photoshop Lightroom for Apple macOS are the appropriate programs for this file. It normally cannot be opened meaningfully as a document in another application.
An .lrdevplugin file is a Lightroom plug-in package, so it cannot normally be converted to another file format. To change its functionality, the plug-in must be edited or replaced with a compatible plug-in rather than converted.
