Motivation

I am using a file naming scheme like: <Category>/<Website>/<Username>/password.gpg. I am using it, because of Android Password Store. Thus, I want to extract the username from the file path.

Proposal

1. The easiest way to add this, would be to add a regex option for the file path. This would make it possible to extract the username from every place I can imagine.
2. It would also be possible to add an option to choose which parent folder to use (so first parent folder, second parent folder, ...)

To be honest, the second option would be nicer and sufficient for most users, but the first is more versatile.
