The command ftype ${file_type}="${path-to-executable_file}" is used in the Windows command prompt to associate a specific file type with a specific executable file.

Here is a breakdown of the command:

• ftype: This is the command used to manage file types in Windows.

• ${file_type}: This is a placeholder for the file type you want to associate with the executable file. For example, you might use .${extension} to specify a specific file extension like .txt or .docx.

• "${path-to-executable_file}": This is the full path to the executable file that you want to associate with the file type. For example, "C:\Program Files\MyApp\myapp.exe".

By running this command, you are essentially telling Windows that whenever a file with the specified file type is opened or executed, it should use the specified executable file to handle it.
