About .psfu Files
PSFU files are specialized PC Screen Font files used by Linux systems. They store bitmap fonts for terminal and console displays.
They follow the MIME type application/x-font-linux-psf and are designed to control how text appears in Linux text mode. They often include a Unicode mapping table to support a wide range of characters.
- Primary Use: Defining and customizing text characters on Linux consoles.
- MIME Type: Recognized as application/x-font-linux-psf, which tells the system that this file contains Linux console fonts.
- Common Utilities: Tools such as the Linux
setfontcommand load these fonts, and font editors like FontForge may be used for viewing or modifying them. - Additional Info: According to FilExt.com, these fonts are not typical image files but system-level resources for rendering textual data in the console.
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 PSFU file?
A PSFU file is a PC Screen Font file used specifically by the Linux kernel for console text modes. It contains bitmap images of characters and typically includes a Unicode mapping table to ensure special characters display correctly in the terminal.
How do I load a PSFU file in Linux?
You can apply a PSFU font to your current terminal session using the setfont command followed by the filename (e.g., setfont myfont.psfu). This command reads the file—identified by the MIME type application/x-font-linux-psf—and uploads the bitmaps to the video card.
Can I open PSFU files on Windows or macOS?
These files are not natively supported on Windows or macOS because they are specific to the Linux console hardware architecture. To view or use the font on these operating systems, you must convert it to a standard format like .ttf or .otf using a font editor.
What software can edit PSFU files?
The most popular tool for editing PSFU files is FontForge, an open-source font editor available for Windows, Mac, and Linux. It allows you to modify individual pixel bitmaps and adjust the Unicode mapping before saving the file.
What is the difference between .PSF and .PSFU?
While both extensions refer to PC Screen Fonts, the .psfu extension explicitly indicates that the file contains a built-in Unicode mapping table. This table tells the system which Unicode character corresponds to which glyph in the font file.
How do I convert a PSFU file to a standard font format?
You can use FontForge to open the PSFU file and generate a standard font. Go to the File menu, select Generate Fonts, and choose a format like TrueType (.ttf) or OpenType (.otf) to make it usable in graphical environments.
What is the MIME type for PSFU files?
The standard MIME type for these files is application/x-font-linux-psf. For more technical details on how this type is handled, you can check the entry on 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.
