Where are Android widgets stored?

Question

MySQL

Tell me, is it possible to implement the ability to save the widget settings to a file, share and import them? Ideally, it would be great if it would be possible, when clicking on a certain file, that an automatic widget with nested settings would appear.
I wrote the program below, and I want to expand the convenience for users.

Write your export-import in an arbitrary format. To use your application when opening a file, use the IntentFilter by extension.
<data android:pathPattern=".*\\.config" />
