What is an ES3 file?

ES3 files mostly belong to E-Szigno / Easy Save 3. The ES3 file extension is used to hold structured data in two distinct scenarios:

Hungarian e-signature data: These files are formatted in XML and store electronic signature information used by Microsec's e-Szignó 3.0 system. They are processed with the E-Szigno XML Signature Formatter. For more details, visit Microsec's website.
Game save data: In this case, the files use the JSON format to capture game state information. This variant is utilized by the Unity game engine as part of the Easy Save 3 system. More information is available at Unity's webpage.

FilExt.com note: When you open an ES3 file, checking its first characters (for example, '<' for XML or '{' for JSON) will help determine which application and process are applicable. It is important to use the appropriate software to view or edit the file, as manual changes can disrupt its structure.

How do you open ES3 files?

You need a suitable software like E-Szigno / Easy Save 3 to open an ES3 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 ES3 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ES3 file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert ES3 files:

E-Szigno / Easy Save 3
See the previous paragraphs to learn more about the main application. ES3 files are often referred to as E-Szigno / Easy Save 3 data files because this type of file is primarily created or used by this software.
Unity game engine / Microsec e-Szignó 3.0
The *.ES3 file extension is primarily associated with Easy Save 3, a data serialization asset commonly used within the Unity game engine. These files typically store game save data in a human-readable JSON format, facilitating cross-platform compatibility and straightforward data management for game developers. Less commonly, *.ES3 can also refer to files generated by Microsec e-Szignó 3.0, a Hungarian e-signature software. These files utilize an XML format to store electronic signature data. This file format is classified as Game Development / Digital Signatures.

ES3 file format:

The file format determines how the data is stored in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). File extension, signature and file format must match; otherwise errors will occur when the file is opened. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below you will find our evaluation of the ES3 files:

The ES3 file extension is rarely used and is primarily used by a single program. The two most popular formats are as follows:

70% of all ES3 files are e-Szigno signed document files, which are based on the XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are text files, so they contain words and text. The file size is in the range of 24 KB to 1 MB. The file type is very recent. Several words can almost always be found in the files, e.g. <?xml version="1.0" encoding="UTF-8"?> and <es:Dossier xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns="http://uri.etsi.org/01903/v1.3.2#" xmlns:e. These files can be linked to tullap, bejegyz and ltoz.

All other ES3 files (30%) have no uniform format. They are often associated with save or data. Drag & drop your file here to see the file format and a preview of your ES3 file!
