SDL Trados Studio is a computer-assisted translation application for Microsoft Windows. The software was developed by SDL, which was later acquired by RWS.
An sdlppx file contains a packaged translation project, including the project data and resources needed to work on it in SDL Trados Studio. It is used to distribute a project to a translator or another project participant.
The package is opened and processed within SDL Trados Studio rather than treated as a document for general-purpose applications. The format remains associated with the Windows desktop versions of the software, now marketed by RWS as Trados Studio.
On Microsoft Windows, open an sdlppx file in SDL Trados Studio using the application's command for opening a project package. The package must be processed by Studio to access the project it contains.
An sdlppx file is a project package, so it normally has no useful direct conversion to another file format. Open it in SDL Trados Studio instead.
Studio can export the translated content or create another project package when the required workflow is complete.
