Describe how to replicate the issue

Hi Team,

After the bug related to the recordDeleteAfter parameter was fixed (see #3557), I've noticed that while recordings are being handled correctly, empty directories are not being deleted after the recordings are removed. This behavior persists even with the updated version.

Could you please look into this? It seems like the cleanup process doesn't account for empty directories, which still remain on the filesystem.

Thank you for your time!
