About .tidisk Files
TIDISK files are binary images designed for the TI-99 V9T9 system.
They use the generic MIME type application/octet-stream, which signals raw binary data.
This format holds a complete sector dump from a TI-99 V9T9 disk, used to replicate or archive disk content.
- Main use case: Backing up and emulating actual TI-99 V9T9 disk drives.
- Additional uses: Data preservation and transfer among vintage computer enthusiasts.
- Software: TI-99 V9T9 emulators and specialized disk management tools can open these files.
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 TIDISK file?
A .tidisk file is a virtual disk image created for the TI-99/4A computer system, specifically designed for use with the V9T9 emulator. It contains a raw binary sector dump of a physical floppy disk, allowing vintage software to be preserved and run on modern hardware.
How do I open a TIDISK file on Windows?
You need a TI-99/4A emulator such as V9T9 or Classic99 to mount and run the disk image. Alternatively, you can use a disk management utility like TI99Dir to view the file catalog and extract specific programs without running a full emulation session.
Can I convert TIDISK files to other TI-99 formats?
Yes, utilities like TI99Dir allow you to convert between V9T9 sector dumps and other common TI formats like PC99 (.dsk) or TIFILES. This conversion is often necessary when moving data between different emulators or archiving tools.
Why is the MIME type for TIDISK generic?
These files are identified by the generic MIME type application/octet-stream because they consist of raw binary sector data without a standardized global header. This classification tells the operating system that the file requires specific software to interpret the binary structure.
How can I extract individual files from a TIDISK image?
You cannot open a TIDISK file with standard archive tools like Zip or 7-Zip. Instead, use TIImageTool or TI99Dir, which understand the proprietary TI-99 file system, to browse the disk content and export individual BASIC programs or binary files to your computer.
Is a TIDISK file the same as a DSK file?
They are functionally similar, but .tidisk explicitly denotes the format used by the V9T9 emulator. While many modern emulators treat .tidisk and raw sector dump .dsk files interchangeably, strict file extensions help older software identify the specific disk geometry.
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.
