About .ndx Files
NDX files are binary files used by Chess Assistant. They store comment index data that helps the software manage chess game annotations.
The MIME type is application/octet-stream, indicating generic binary content.
- Main use: Quickly locating and indexing commentary in chess databases
- Functionality: Organizing game annotations for efficient retrieval
- Usage: Accessed by Chess Assistant software and related chess analysis tools
Based on information from FilExt.com, NDX files play a key role in managing comment indexes within Chess Assistant.
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 NDX file used for?
An NDX file is primarily an index file used by the Chess Assistant software. It stores binary data that points to comments and annotations within a chess database, allowing the program to quickly locate and display analysis during a game review.
How do I open an NDX file?
You cannot open an .ndx file directly to view its contents. It is a support file that Chess Assistant loads automatically in the background when you access a database. Attempting to open it manually will usually prompt Windows to ask for an application or display garbled text.
Can I convert an NDX file to a text format like PDF or TXT?
No, you cannot convert an .ndx file directly because it only contains internal indexing numbers, not readable text or chess moves. To save chess data in a readable format, use the Export feature within Chess Assistant to save games as .pgn or .cbh files.
What happens if I delete an NDX file?
If you delete this file, Chess Assistant may lose the ability to find comments or annotations associated with specific games. However, the software usually includes database maintenance tools that can scan the main data files and regenerate the index.
Why does the file look like random symbols in Notepad?
NDX files are binary files, meaning they are written in machine code rather than plain text. Opening them in a text editor like Notepad reveals unreadable characters. Do not save changes in a text editor, as this will corrupt the index.
Are there other programs that use NDX files?
Yes, .ndx is a common extension for index files in older database systems like dBASE or Paradox. If you do not use Chess Assistant, your file likely belongs to a legacy database application, but the internal format will be different.
What is the MIME type for NDX files?
Since NDX files are proprietary binary data, they generally use the generic MIME type application/octet-stream. This instructs the operating system to treat the file as a stream of bytes rather than a specific document type. You can find more details about binary types 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.
