You're here because you have a file that has a file extension ending in .xfo. Files with the file extension .xfo can only be launched by certain applications. It's possible that .xfo files are data files rather than documents or media, which means they're not meant to be viewed at all.

Files using the .xfo extension are actually forms that come in the format of XSL-FO markup language. These are important files because they contain definitions and information about the formatting process of XML data which are used on screen, for printing or other media types. The Digiforms Document Designer can be used to open .xfo files. This software is known as tool for graphic designing and it is mostly used for the creation and maintenance of documents, forms, reports, etc. With the use of this software, users can design templates, input memos, translate forms into a different language, and add images and logos to documents, and a lot more. Aside from that, the 602XML Filler can also be used to opne.xfo files. This application is used for filling out forms whether users fill them out online or offline. The application does not only allow filling out of forms but it is also packed with other features such as saving the file to the user’s hard drive so they can get back to it later, digital signing of forms, converting the forms to PDF files, performing calculations automatically, and a lot more. Offline and online applications can use these .xfo files provided they are compatible applications that support the said files.

Launch a .xfo file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .xfo file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .xfo files aren't yet associated with it. In this case, when you try to open a .xfo file, you can tell Windows which application is the correct one for that file. From then on, opening a  .xfo file will open the correct application.

Be careful not to rename the extension on .xfo files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .xfo. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
