About .emacs.desktop Files
EMACS.DESKTOP files are configuration files for GNU Emacs. They are written in Emacs Lisp code, which explains the MIME type text/x-common-lisp used for them.
They are mostly used for saving and restoring the workspace state of Emacs. This means the file records open buffers, window sizes, and other session details so that Emacs can reinitialize your work environment when restarted.
- Session Restoration: Automatically saves your open files and buffers.
- Configuration: Contains Emacs Lisp code that sets up personal settings.
- Editing: Can be opened and modified using Emacs or any plain text editor like Notepad++ or Sublime 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 an .emacs.desktop file?
An .emacs.desktop file is a session configuration file used by the GNU Emacs text editor. It saves the state of your workspace, including open files, cursor positions, and buffer history, allowing you to resume your work exactly where you left off upon restarting the editor.
How do I open an .emacs.desktop file?
You generally do not open this file manually; instead, GNU Emacs reads it automatically at startup if desktop-save-mode is enabled. However, since it contains plain text and Lisp code, you can view or edit it using any text editor like Notepad++, VS Code, or Vim.
How do I create an .emacs.desktop file?
Emacs generates this file automatically when you enable the desktop saving feature. To activate this, add the line (desktop-save-mode 1) to your Emacs initialization file (often called .emacs or init.el), which tells the editor to save session data to .emacs.desktop when you exit.
Why is the .emacs.desktop file hidden on my computer?
On Unix-based operating systems like Linux and macOS, filenames starting with a dot (.) are treated as hidden system files. To see this file, you must enable the "Show Hidden Files" option in your file manager or use the ls -a command in a terminal.
Is it safe to delete an .emacs.desktop file?
Yes, it is safe to delete this file; doing so will simply reset your saved session state. The next time you launch Emacs, it will start with a fresh environment rather than restoring your previously open windows and buffers.
What is the MIME type associated with .emacs.desktop?
The file is typically associated with the MIME type text/x-common-lisp because it is written in Emacs Lisp. You can find more information about this media type and its handling on mime-type.com under the text/x-common-lisp section.
Can I manually edit the contents of .emacs.desktop?
Yes, advanced users can edit the file to manually remove specific buffers or adjust settings. Since the file format is valid Emacs Lisp code, be careful to maintain correct syntax so that Emacs can parse the file correctly during startup.
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.
