What is a ZPF file?
A .ZPF file can belong to several different software applications. The most common use is a Zumtobel Product File or Thorn Lighting Product File. The Zumtobel Group uses this file to store lighting product data in a standard XML format.
Other software also uses the .ZPF extension. The Ocarina of Time Randomizer uses it as a Zelda Practice File, which is a game randomizer patch compressed with zlib. Structural engineering software like AceCad StruCad uses the extension for detailing projects stored as standard ZIP archives. Additionally, AutoDesSys uses it for the Form•Z Preferences File.
How to open ZPF files?
Because a .ZPF file has multiple possible meanings, we recommend using viewer.online/zpf to identify the actual format of your file. If it is an XML lighting file, you can view it with any text editor. If it is a ZIP archive from StruCad, you can extract it with archive tools. If it is a game patch, you need the specific randomizer utility.
Inspecting files with viewer.online
viewer.online/zpf analyzes .ZPF files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
Because .ZPF files use the known XML format, viewer.online/zpf can safely open and display them online, eliminating compatibility problems.
