What is a .SDLXLIFF file?

The file extension .SDLXLIFF represents an SDL Trados XLIFF Localization File. This type of file is specifically created by SDL Trados, which is a software application designed for translating various types of content. The .SDLXLIFF file is fundamentally based on the XLIFF standard, which stands for XML Localization Interchange File Format. XLIFF is a widely recognized format used to standardize the way localizable data is passed between tools during a localization process.

However, .SDLXLIFF files include some unique, proprietary extensions that are specific to SDL Trados. This means that while they are based on a standard format, they also contain additional data that can only be interpreted by SDL Trados software.

These files are particularly useful because they can be converted into another format known as .TTX. This conversion is done within SDL Trados itself. The .TTX format is another translation format that is more commonly used, making it easier to exchange data with others who might not be using SDL Trados.

To open an .SDLXLIFF file, you will need to use SDL Trados Studio, which is the specific program designed to handle this file type. SDL Trados Studio provides the tools necessary to work with, edit, and manage .SDLXLIFF files effectively during the translation process.
