How to: Change or Add a Default Editor
You might want to choose which editor you use to work on your files. For example, you can open .txt files in WordPad if you like. Editors and files are associated with each other based on the file's type as indicated by the file's extension. After you change the default editor for a file type, every file of that type opens in the new default editor.
Note
If you try to open a file with an extension that is not associated with a specific editor, the file is opened in the text editor.
To change the default editor for an existing file
On the File menu in Visual Studio, choose Open and then select File.
In the Open File dialog box, select a file of the type you want to change.
For example, if you want to change the default editor for text files, select a .txt file.
Still in the Open File dialog box, click the down arrow next to the Open button, and then select Open With.
