What is MIME type "image/x-ioca"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
image/x-ioca is a MIME type for images using the IBM IOCA format. It tells your system that the file is a specialized image meant for IBM environments. This is used with ICA files.
This MIME type signals that the image file may need proprietary software to be viewed correctly. It serves as a container for visual data like icons or other graphics used within IBM systems.
- Primary use: Storing and transporting image data within IBM applications.
- Key characteristic: The "x-" prefix shows it is experimental or vendor-specific.
- Additional details: It might not be widely supported by common image viewers on PCs.
- Practical note: Opening such files may require IBM’s specialized tools or conversion software.

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 are multiple MIME types listed for one extension?
Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
