About .aux Files
AUX files are auxiliary files produced during TeX document processing. They are plain text files identified by the MIME type text/x-stex and store information needed for document compilation.
Main Use: These files hold data like cross-reference labels, citation keys, and table of contents entries generated in one run and used in subsequent runs of TeX or LaTeX compilers.
- Intermediate Storage: They save meta information for later use in document references.
- Compilation Aid: The data helps resolve cross-references, enabling accurate labelling and indexing.
- Debugging: Advanced users may review AUX files to troubleshoot compilation errors.
They are automatically created and updated by software such as TeX Live, MiKTeX, TeXworks, or TeXmaker. Although you can open them with any text editor (like Notepad), changes should be made with caution since they are integral to the compilation process.
Based on information from FilExt.com, AUX files play a vital role in ensuring that multiple passes of document processing work smoothly.
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 an .aux file?
You can open .aux files with any standard text editor, such as Microsoft Notepad, Apple TextEdit, or code editors like VS Code. However, these files are intended to be read by LaTeX software (like TeXworks or Overleaf) rather than humans, so manual editing is rarely necessary.
Can I delete .aux files safely?
Yes, you can safely delete .aux files without losing any source data. They are temporary files automatically generated by the LaTeX compiler to store cross-references; if you delete one, the software will simply create a new one the next time you compile your document.
How do I convert an .aux file to PDF?
You cannot convert an .aux file directly to PDF because it only contains metadata like labels and citations, not the document content. To create a PDF, you must compile the original .tex source file using a distribution like MiKTeX or TeX Live.
Why does my .aux file cause compilation errors?
Sometimes an .aux file can become corrupted or contain outdated reference data, causing the LaTeX compiler to crash or report errors. The standard fix is to delete the .aux file entirely and recompile the main document to generate a fresh, error-free version.
What is the MIME type for .aux files?
These files are typically associated with the MIME type text/x-stex or sometimes application/x-tex depending on the server configuration. For specific details on handling TeX-related types, check the text/x-stex entry on mime-type.com.
Why is the .aux file empty?
An .aux file may appear empty or missing if the LaTeX compilation process failed immediately or if the document contains no cross-references, citations, or table of contents. Ensure your main .tex file compiles successfully, as the auxiliary file is written during that process.
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.
