About .gal Files
GAL files are binary files used by the DeluxePaint Gallery system.
They typically store collections of images and related data in a format recognized by application/octet-stream MIME type.
- They are used to group multiple pictures in one file.
- They serve galleries created with DeluxePaint software.
- The file content is binary, which means it is not plain text.
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 .gal file?
A .gal file is typically a gallery file created by Electronic Arts DeluxePaint, a classic graphics editor popular on Amiga and MS-DOS systems. These binary files function as containers that store multiple images or sprites in a single package. Because they are binary, they are often identified by the generic application/octet-stream MIME type.
How can I open a GAL file on Windows 10 or 11?
You can open these files using specialized retro image viewers such as XnView MP or Recoil (Retro Computer Image Library). Alternatively, you can run the original DeluxePaint software inside an emulator like DOSBox or WinUAE to view the gallery in its native environment.
Can I convert GAL files to standard images like PNG or JPG?
Yes, if you open the file in a modern viewer like XnView, you can usually use the "Save As" or "Export" feature to convert the contents to PNG, JPG, or BMP. If you are using an emulator, you may need to take screenshots or use the emulator's built-in tools to capture the images.
Why does the file look like gibberish in Notepad?
DeluxePaint Gallery files are binary, not text-based, meaning they contain compiled image data that text editors cannot interpret. Opening a .gal file in Notepad will display unreadable characters; you must use a compatible graphics program to view the images correctly.
Are there other formats that use the .gal extension?
Yes, the .gal extension is also used by GenePix for Array List files (which are text-based) and occasionally for Global Address Lists in email systems. If your file opens as readable text containing coordinate data, it is likely a GenePix file rather than a DeluxePaint image gallery.
What MIME type should be configured for serving GAL files?
Since there is no specific standard MIME type for DeluxePaint files, they should usually be served as application/octet-stream. This instructs the web browser to treat the file as generic binary data and initiate a download, rather than attempting to render it as text or HTML. You can learn more about this type at mime-type.com.
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.
