hello sir.
After removing the application, some questions arose.
After uninstalling with extension Looking at the application panel, the application folder? the same thing remains as it is.
(For example xwiki:\dashboard…)
When this application is entered, the delete button does not exist, so it cannot be deleted. (admin page exists.)
If you reinstall this application, you will find two application folders…
If you delete it with extension, one folder still exists as above.
So I have some question, How can I delete a folder like the one above?
