Thanks for the reply and thanks for the help. With this being the intended function, storage locations of docker containers such as Minio will always be left with hundreds or thousands of empty folders after running the mover. Nearly every file created within a Minio storage location is created within multiple nested folders. As new files are added, they are placed within newly created nested folder structure. Therefore it would seem the tuning plugin will always leave many empty folders after the mover runs. Is there another mechanism to remove the empty folders left behind or should I look towards writing a script to clean up those empty folders?
