Which MIME types are related to file extension ".ts"?
The .ts file extension is associated with 6 MIME types:
application/xml, text/xml, video/mp2t, application/typescript, application/x-typescript, text/x-typescript.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .ts Files
TS files are multi-purpose files that serve different functions depending on their MIME type.
- Video: TS files are known as MPEG-2 Transport Streams with the MIME type video/mp2t. They deliver broadcast-quality video and audio streams. Media players like VLC and MPC-HC can play these files.
- Programming: TS files also hold TypeScript source code. They use MIME types like application/typescript, application/x-typescript, and text/x-typescript. Developers write and compile these files into JavaScript using IDEs such as Visual Studio Code.
- Localization: Additionally, TS files can be Qt translation source files using XML formats (application/xml or text/xml). They support language translations for Qt-based applications. Tools like Qt Linguist edit them.
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
Why does my .ts file open as text instead of a video?
The .ts extension is shared by two completely different formats: MPEG-2 Transport Stream video and TypeScript source code. If your file opens in a text editor showing code, it is a script file (MIME type application/typescript). If it contains binary data but opens as text, you likely need to right-click the file and select "Open with" to choose a media player like VLC.
How do I play a .ts video file on Windows or Mac?
The most reliable way to play .ts video files is using VLC Media Player, which supports the video/mp2t format natively. Windows Media Player and QuickTime often fail to play these files without installing additional codec packs (like K-Lite Codec Pack).
How can I convert a .ts file to MP4?
You can use free video conversion software like HandBrake or command-line tools like FFmpeg. In HandBrake, simply drag the .ts file into the window and choose the "Fast 1080p30" preset (or similar) with MP4 as the output format. This converts the stream into a more widely compatible container.
How do I run a TypeScript .ts file?
You cannot run a .ts file directly in a browser or Node.js; it must be compiled into JavaScript first. Install the TypeScript compiler via npm (npm install -g typescript) and run the command tsc filename.ts in your terminal. This generates a .js file that allows the code to run.
What is the correct MIME type for .ts video files on a server?
When serving video streams via HTTP, you should configure your server to use the MIME type video/mp2t. If the server incorrectly sends a text-based MIME type, browsers may attempt to display the binary video data as garbled text or force a file download instead of streaming it.
Can I edit a .ts file with Notepad?
Yes, if the file is TypeScript code or a Qt Translation file (XML), you can edit it with Notepad, though code editors like Visual Studio Code are recommended. However, if the file is a video, opening it in Notepad will show unreadable symbols and saving it will corrupt the video data.
What is a Qt .ts file?
In the context of the Qt application framework, a .ts file is an XML-based translation source file. It stores text strings extracted from the software for localization. These files are typically edited using Qt Linguist and utilize generic XML MIME types like text/xml or application/xml.
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.
