How to open XCU files

You need a suitable software like OpenOffice.org to open an XCU 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 XCU file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a XCU file directly in the browser:.

XCU format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The file format can be deduced from the file extension and the signature. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the XCU files looks like this:

XCU is rarely used as a file extension and is primarily used by a single program. The two most common formats are as follows:

80% of all XCU files belong to StarOffice UNO Configuration. The files are using the common file format XML. 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. The contents of these files can even be read by a human. A typical file size is 200 KB. The file type was created 10 years ago, but is still used today. The files contain the following words: <?xml version="1.0" encoding="UTF-8"?> and <oor:items xmlns:oor="http://openoffice.org/2001/registry" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">. The file name registrymodifications.xcu or Addons.xcu is characteristic of these files. Such files are related to dictionaries.

The remaining 20% of all XCU files are different files with different signatures. Drag & drop your file here to see the file format and a preview of your XCU file!
