Deleting single folders - not only their content

I would like to have an option to delete a whole folder - completely, with all enclosed files and subfolder. This works already fine.

But I would also have the feature, to delete this folder by itself.

I can select a single file to be deleted, why not a single folder too?

Now, I found out, how to delete a whole folder.

But it doesn't work on my end, since this folder is marked as ReadOnly, since I want to delete the folder C:\Users\Tahtu\Searches.
