What is an XLIF file?

XLIF files mostly belong to SDL Trados Studio, memoQ, Across Language Server, and other CAT tools. An XLIFF (XML Localization Interchange File Format) file is a localization file format designed specifically for exchanging localization data between different Computer Assisted Translation (CAT) tools and other software. It's an XML-based format that stores text to be translated, along with other information such as the text's context, formatting, and any existing translations. XLIFF files are commonly used in software localization, website translation, and other translation projects. They allow translators to work on localized text while preserving the original formatting and structure of the document. The format supports various features such as translation memory integration, terminology management, and quality assurance checks, making it a crucial part of the localization workflow. XLIFF files ensure consistency and efficiency in translation projects by providing a standardized way to exchange localization data between different tools and stakeholders.

How do you open XLIF files?

You need a suitable software like SDL Trados Studio, memoQ, Across Language Server, and other CAT tools to open an XLIF file. You need a suitable software like SDL Trados Studio, memoQ, Across Language Server, and other CAT tools to open an XLIF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your XLIF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a XLIF file directly in the browser:.

Can't Open Your .XLIF File? Try These Steps

Because .XLIF files are specialized localization formats used by various translation tools, they aren't universally openable.

1. Identify the Source: Receiving this file from a translation agency or a software developer strongly suggests it is an XML Localization Interchange file.
2. Check the Header: Open the file in a basic text editor to inspect the opening lines:
   • Seeing <?xml version="1.0"?> or <xliff> indicates a standard, readable XML-based translation document.
   • Seeing "PK" or garbled characters suggests a zipped or proprietary variant.
3. Use the Original Software: Opening the file usually requires a Computer-Assisted Translation (CAT) tool like SDL Trados Studio, memoQ, or Across Language Server; if unsure, ask the sender.
4. Use this Webpage: Drag and drop your file onto this page to detect its format, extract readable text and metadata, and preview the contents.

XLIF file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. So you need a detailed analysis of a file to find out the format and the associated program. Our evaluation of the XLIF files looks like this:

The XLIF file extension is rarely used and includes different formats for different programs. The file formats most commonly found in XLIF files are:

• 55% of all XLIF files are Leica XLIF document files, which are based on the XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. If you open these files in a text editor, you can view and read the content yourself. The average file size is 12 KB with most files being between 10 KB and 80 KB in size. This file type is based on cutting-edge technology. The files contain the following words: <?xml version="1.0" encoding="utf-8"?>, <LMSDataContainerHeader Version="2", ApplicationDescription, ApplicationVersion, Element Name, LMSIOManager and Visibility. Such XLIF files store data about image and overlay.
• 40% of all XLIF files are based on the well-known XML file format. The content consists of readable text data, which can be read using a text editor. The files are often between 9 KB and 16 KB in size. The files contain the following words: <?xml version="1.0"?>, <LMSDataContainerHeader Version="2", ApplicationDescription, ApplicationVersion, Element Name, LMSIOManager, Visibility="1" CopyOption="1" and UniqueID. An example of a file name is Image001.xlif.
