About .ppm Files
PPM files are a type of image file used for storing pictures in a simple, portable format.
They follow the Netpbm standard and often use the MIME type image/x-portable-pixmap.
These files save color images using a plain text header and a binary section. This makes them easy to create and read by software.
Based on information from FilExt.com, here are some key points about PPM files:
- Simple Structure: They have a clear header and straightforward data format.
- Versatility: They belong to the Netpbm family, which also includes portable anymap, bitmap, and graymap files.
- No Compression: They do not use compression. This means larger file sizes but simpler processing.
- Usage in Unix Systems: They are popular in Unix and Linux environments for quick image handling.
- Editing and Viewing: Applications like ImageMagick, GIMP, and IrfanView can open and edit these files.
They are part of the broader Netpbm formats ecosystem, which includes related MIME types like image/x-portable-anymap, image/x-portable-bitmap, and image/x-portable-graymap that serve similar purposes for different image types.

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.

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.
