Is it possible to list all the applications on a machine that can open a specific file type, using only the files extension? for example if I have a text file (.txt), I want a list of all applications that can open .txt files.
Check out the HKEY_CLASSES_ROOT
hive in your registry. It's all in there.
没有可以打开我所知道的特定文件的每个应用程序的主列表。
I am assuming you are talking about Windows machines...
You can only go so far as listing the applications that are registered has to able of handling a specific file extension (the same applications that show up when you right click and select "Open With"). This is somewhere in the Windows Registry.
I would suggest you to check on the microsoft documentation, or open your registry and start searching for known extensions.
