What is an EPZ file?

EPZ files mostly belong to PCM600.

The EPZ file is used in specialized applications. In one format, it stores protection relay settings for devices made by companies such as ABB and Siemens. These files hold configuration data that is loaded using dedicated software like PCM600.
In another format, an EPZ file is a project file that uses a compressed ZIP archive to store data for Epidata projects. This version is managed by tools from the Epidata system.

Key points provided by FilExt.com include:

• Use the vendor-specific software (PCM600 for relay configurations or the Epidata tool for project files) to open the file.
• Review the file documentation provided by the manufacturer before making changes.
• Keep backup copies of your files to prevent data loss.

FilExt.com tip: For further details on relay settings, visit Secheron. For Epidata project files, see Epidata.

How to open EPZ files

You need a suitable software like PCM600 to open an EPZ 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 EPZ file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a EPZ file directly in the browser:. Just drag the file onto this browser window and drop it.

EPZ file format details:

To view or edit EPZ files you need to know the file format, because it determines how the data in this file is stored. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the EPZ files is as follows:

The EPZ file extension is not widely used. Such a file is primarily used by a single program. The file formats most commonly found in EPZ files are:

• 70% of all EPZ files start with the magic bytes EP, which are always the first bytes of this file format. If you open these files in a text editor, you will see only illegible characters. Most of these files are 8 KB to 120 KB in size. This file type is based on cutting-edge technology. These files are often associated with diff, transformer, outgoing, found, incomer, feeder, panel and trafo.
• 25% of all EPZ files use the ZIP format, that is, an EPZ file includes multiple compressed files. EPZ files contain from 1 to 3 compressed files. File names are e.g. ecad.json and project-source.txt. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. EPZ files are between 4 KB and 1 MB in size. Several words can almost always be found in the files, e.g. RPPJMNL and ecad.jsonUT. An example of a file name is -_2020_06_01 10_30.epz or -_2020_06_01 10_30_2020_06_01 10_30.epz. Files like these have the following tags: data.

All other EPZ files (5%) have different formats. These files are often connected to order or left. Drag & drop your file here to see the file format and a preview of your EPZ file!
