The sdlxliff file extension is associated with SDL Trados Studio, a computer-assisted translation environment for editing, reviewing and managing translation projects. SDL Trados Studio is developed by RWS and runs on Microsoft Windows.
An sdlxliff file stores the source and translated text in segments, along with translation status, formatting information and other translation-related metadata. The format is based on XLIFF with extensions used by Trados Studio.
SDLXLIFF files are working files within a Trados Studio translation project.
Open the sdlxliff file in SDL Trados Studio on Microsoft Windows. It can be opened as a document in the application or added to a Trados Studio project.
Other applications may not preserve the file's translation data and metadata correctly, so SDL Trados Studio is the appropriate program for editing it.
An sdlxliff file is normally processed rather than converted. In SDL Trados Studio, complete or review the translation and generate the translated target document in the required document format.
Generic XML or XLIFF conversion can lose Trados Studio-specific translation information. Use SDL Trados Studio when the bilingual file itself must be preserved.
