What is an IDENTIFIER file

IDENTIFIER files mostly belong to Microsoft Windows. IDENTIFIER files are specialized files that hold information about a file’s origin. They record metadata details about how a file was downloaded, which helps the operating system manage security and validate file sources.
In many cases, these files are used by Microsoft Windows to maintain download history and track the source of files. For more information on how Windows handles these records, see the details on the Microsoft Windows site.
Some IDENTIFIER files also use an HTML structure to store web page content. This format can include elements like a sign-in form; such files are crafted as standard HTML and can be rendered in a web browser like Google Chrome.

Metadata records: They log file download origin data for system-level checks.

HTML content: They sometimes embed HTML code to display web-based interfaces.

FilExt.com tip: These files are primarily managed by the system and are not intended for manual editing. Proper applications should be used to view or analyze them.

How can I open an IDENTIFIER file?

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

Programs that open and convert IDENTIFIER files:

Microsoft Windows
See the previous paragraphs to learn more about the main application. IDENTIFIER files are often referred to as Microsoft Windows data files because this type of file is primarily created or used by this software.
Internet Explorer (Zone Identification Information) by Microsoft Corporation
You won't normally see this file extension and if you do it should be attached to a filename with a colon and "zone" before it (e.g., FILENAME.DPC:ZONE.IDENTIFIER). This type of file name might be revealed by a rootkit identification program. When you use Internet Explorer to download a file that can have executable content (.DOC files, for example, can have executable macros in them) IE adds an NTFS Alternate Data Stream named ZONE.IDENTIFIER to the file. The ADS subsystem allows additional data to be linked to a file. The additional data, however, is not always apparent to the user. If you open a Command Prompt window, navigate to the folder containing the file, and command MORE < FILENAME.DOC:ZONE.IDENTIFIER (substitute the name of the file for FILENAME.DOC in the command) then you should see the contents of the ADS attachment which should be a couple of lines identifying the assigned Internet Zone when the file was downloaded and saved. If you trust this file you can right click it, select properties, and on the general tab click the unblock button. This file format is classified as Text. Related links: CKNOW Info Page on NTFS ADS

IDENTIFIER file extension format:

A file format defines how the data in the file is structured. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the IDENTIFIER files is as follows:

The IDENTIFIER file extension is primarily used by a single program. The following file formats are most commonly found in IDENTIFIER files:

95% of all IDENTIFIER files are Microsoft Zone Identifier files, which are using the popular config file format. A configuration file is used by computer software to store settings. It consists of a text-based content with a structure and syntax comprising key–value pairs for properties, and sections that organize the properties. These files are text files, so they contain words and text. Most of these files are 26 bytes to 300 bytes in size. The file type was developed only in the last few years. Certain words are almost always found in the files, such as [ZoneTransfer], ZoneId=3, HostUrl and ReferrerUrl. Such files sometimes refer to movie, zone, docx, data, xlsx, jpeg, pptx, report, house, large and video.

The remaining 5% of all IDENTIFIER files are files with no common format. Just click the "Choose your .identifier file to view" button on this page to find out what your IDENTIFIER file is.
