Why my .ts file get saved as MPEG2 TS format when i want it to be saved as typescript

Question

I'm new to the development, currently working on Angular 2 I came across a problem while saving the .ts (typescript) file in my computer (Win 7). I have run the commands using npm:

>npm install typescript

but when I try to save the text file to .ts file it creates MPEG 2 TS file. How to resolve this problem. Please help!

Answer 1

It doesn't get saved in MPEG-2 TS format. Windows just interprets the .ts extension as MPEG-2 TS and shows a video file like icon for your .ts file. You can ignore that.

Answer 2

The fact that windows treats .ts files as video is super annoying for anyone working with typescript daily.

I couldn't find a way to change this in regedit, but I found an app called FileTypeMan.

I used it to set mime type to text/plain and perceived type to text.

Now the explorer doesn't try to generate a video thumbnail when i open a folder with typescript files any more.

I don't like that I had to download a program for this, but at least it doesn't need admin rights to run.

If someone find a way to do it with only regedit please share.

You can modify how Windows opens any file, with these steps (in this case, a TypeScript source code file):

• Right click on the file (just open the context menu)
• Click in Properties

• You will see the properties configuration window (showing second section in the General tab):

  

• Click in the Change... button

• Then, select your preferred text/code editor or IDE

  

• In this case, I have selected Visual Studio Code:

  

• Click in OK, and that is all. Windows 10 will read all .ts files as source code files.
