ZFO File Extension

Have a problem opening a .ZFO file? We collect information about file formats and can explain what ZFO files are. Additionally we recommend software suitable for opening or converting such files.

What is the .ZFO file type?

The .zfo extension is used in conjunction with the 'Extensible Stylesheet Language Formatting Objects (XSL-FO) Form, Zipped' file type to denote XSL-FO zipped form files (.zfo). With the status of a W3C Recommendation (latest version 1.1), XSL-FO is a unified markup language for formatting XML documents, mainly for printing and press publishing.

 A generic XSL-FO form is an XML-based interactive (fillable) document that allows generation of a pre-formatted final PDF or other document, incorporating the data filled in by the user.

A .zfo file is a ZIP archive with an XSL-FO form inside. Like any other ZIP archive, a .zfo file can be password-protected with or without encryption. Non-zipped XSL-FO forms are usually saved with the .fo extension.

ZFO forms can be filled out, saved, printed etc. with the use of form-filler software tools. Additionally, any .zfo file can be opened and its contents viewed and extracted with an archive manager.
