What is a ZDP file?
A .ZDP file is primarily an Avery DesignPro Label File created by Avery Dennison. Users create these files to design and print labels, business cards, and dividers. While this is the most common use, a .ZDP file can also be a surface metrology data package created by Zygo Corporation (stored as a ZIP archive) or a password manager database file created by Zebra-Media or ZoneAlarm (stored as a JetDB database).
How to open ZDP files?
You can open an Avery DesignPro Label File using the original Avery DesignPro software. However, Avery Dennison discontinued this software and replaced it with a web application. This makes older .ZDP files difficult to open today.
If you do not have the software, viewer.online/zdp analyzes .ZDP files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because the .ZDP extension has multiple possible meanings, viewer.online/zdp helps you identify the actual format of your file.
Software and tools
The primary tool for the label format is Avery DesignPro. For the password manager databases, you need Zebra-Media Password Manager or ZoneAlarm. For surface metrology data, you need Zygo software. Advanced users can sometimes rename the metrology .ZDP file to .ZIP and extract it using 7-Zip.
Best practices and troubleshooting
If you cannot open a .ZDP file, do not change the file extension manually unless you know it is a compressed archive. Since a .ZDP file might be a database or a document structure, changing the extension can corrupt the data. Instead, use an inspection tool to verify the internal file signature first.
Summary
A .ZDP file is typically an Avery DesignPro Label File, but it can also hold metrology data or passwords. Because .ZDP files use the known DOC format, viewer.online/zdp can safely open and display them online, eliminating compatibility problems.
