About .pkinfo Files
PKINFO files are used to store metadata for ArcGIS packages in an XML format (MIME type: text/xml).
They carry essential details about the contents of an ArcGIS package, such as data descriptions and configuration settings.
This file format helps ArcGIS software, like ArcGIS Desktop and ArcGIS Pro, to process and verify package information.
- They provide descriptive package information.
- They assist in ensuring data integrity.
- They aid in managing spatial data efficiently.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .pkinfo file?
A .pkinfo file is a metadata file used by Esri ArcGIS software. It resides inside ArcGIS packages (such as Map Packages or Layer Packages) and contains essential XML-formatted information describing the package contents, credits, and usage constraints.
How do I open a .pkinfo file?
Since .pkinfo files are formatted as standard XML, you can view their contents using any text editor, such as Microsoft Notepad, Notepad++, or Visual Studio Code. However, they are designed to be processed automatically by ArcGIS Pro or ArcMap rather than opened manually by users.
Why do I see a .pkinfo file after extracting a ZIP?
ArcGIS packages (like .mpk or .lpk) are technically compressed archives. If you use a file archiver like 7-Zip or WinRAR to extract a package, you will see the internal structure, which includes the .pkinfo file acting as a manifest for the spatial data.
What is the MIME type for .pkinfo?
Because the file content is structured as Extensible Markup Language, it utilizes the text/xml MIME type. For more information on how media types are categorized, you can visit mime-type.com.
Can I convert a .pkinfo file to PDF or DOCX?
No, converting a .pkinfo file to a document format like PDF is not practical because it contains configuration code, not readable prose. If you simply want to view the data structure in a more readable way, you can rename the file extension to .xml and open it in a web browser.
Is it safe to delete the .pkinfo file?
No, if you are working with an unpacked ArcGIS package, you should not delete the .pkinfo file. ArcGIS relies on this file to verify data integrity and read package descriptions; deleting it may render the package unreadable or corrupt.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
