About .gg Files
GG files are compressed image files developed by the KoalaPainter application. They store artwork in a specialized format that uses a custom compression algorithm.
The MIME types image/x-koa and image/x-koala tell the system to treat these as image files with KoalaPainter-specific compression.
- Main Use: Saving and sharing digital artwork created in KoalaPainter.
- File Nature: Contains compressed image data.
- MIME Type: Helps operating systems and software identify the file as a KoalaPainter image.
- Software Support: Best opened or edited with KoalaPainter. Other image viewers or editors may require additional plugins.
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
How do I open a .gg image file on Windows?
You can open KoalaPainter .gg files using specialized image viewers that support retro formats, such as XnView MP or RECOIL (Retro Computer Image Library). Since these are Commodore 64-era graphics, standard viewers like Microsoft Photos will not recognize them.
How can I convert a .gg file to JPG or PNG?
Use a multi-format converter like XnView or an online tool specifically designed for retro graphics to export the file. Once opened in these programs, you can use the "Save As" or "Export" function to save the image as a standard JPG, PNG, or BMP.
Why is my .gg file not opening as an image?
The .gg extension is also commonly used for Google Desktop Gadgets or GameGuardian scripts. If your file is a ZIP archive containing HTML/XML (Google Gadget) or a text file with Lua code (GameGuardian), it is not a KoalaPainter image.
What is the correct MIME type for KoalaPainter .gg files?
When hosting these files on a web server, you should use the MIME type image/x-koa or image/x-koala. You can learn more about configuring these types at mime-type.com.
Can I edit .gg files in Adobe Photoshop?
No, Adobe Photoshop does not natively support the proprietary compression used by KoalaPainter. You must first convert the .gg file to a compatible format like TIFF or PNG using a third-party utility before editing it in Photoshop.
Are .gg files dangerous to open?
KoalaPainter image files are generally safe as they contain only graphic data. However, because the extension is also used for scripts (GameGuardian) and executable gadgets (Google Desktop), you should verify the source of the file before running it.
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.
