Is it possible to recover a deleted folder without dancing with a tambourine?

Question

linux

Deleted the folder a few days ago. Its name is known (the content, i.e. the name of the files is not known).
Is there an easy way to restore the contents of a folder? No write operations have been performed on this external drive yet.
Ubuntu 16.04, the folder was on an external drive.

Answer 1

I list as the complexity increases:
- call a familiar fairy
- restore from backup
- pay for the work of a data recovery company
- do this work yourself
