About .stb Files
STB files are binary files used as AutoCAD Named Plot Style Tables. They store printing style definitions for CAD drawings. The file uses the application/octet-stream MIME type, which shows it is in binary format and not meant for manual editing.
- Main use: Standardizing print outputs in AutoCAD by linking style names to printing properties like line weight and color.
- Other uses: Supporting similar style definitions in other CAD programs.
- Software: Open and edit these files with Autodesk AutoCAD or compatible CAD applications.
Based on information from FilExt.com, STB files help users maintain consistent printing settings in their design workflows.
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 STB file used for?
An STB file is an AutoCAD Named Plot Style Table that stores print settings such as line weight, color, and dithering. unlike color-dependent styles, STB files allow users to assign specific print styles to objects or layers by name, offering more flexibility in CAD plotting.
How do I open and edit an STB file?
You cannot open an STB file with a standard text editor because it uses a binary format. To edit it, you must use the Plot Style Table Editor built into Autodesk AutoCAD. You can access this by typing STYLESMANAGER in AutoCAD and double-clicking the desired file.
What is the difference between STB and CTB files?
CTB (Color-Dependent) files map print styles strictly to the color of objects, whereas STB (Named) files map styles to names that can be applied to any object regardless of its color. This distinction allows STB files to decouple the visual color on the screen from the final printed output.
How can I convert an AutoCAD drawing to use STB files?
To switch a drawing from using CTB to STB styles, use the AutoCAD command CONVERTPSTYLES. If you need to convert an existing CTB file into an STB file for use in this process, use the CONVERTCTB command.
Where should I save STB files so AutoCAD recognizes them?
STB files must be placed in the designated Plot Styles folder. You can find this location on your computer by opening AutoCAD and running the STYLESMANAGER command, which opens the correct folder in Windows Explorer or macOS Finder.
What is the MIME type for STB files?
STB files are typically identified with the generic binary MIME type application/octet-stream. For more details on binary streams, you can verify definitions at mime-type.com.
Why is my STB file not showing up in the Plot dialog?
If your STB file is in the correct folder but not visible, your drawing is likely set to use Color-Dependent (CTB) styles. You can check the system variable PSTYLEMODE; if it is set to 1, the drawing expects CTB files, and you must convert it to use Named Plot Styles (STB).
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.
