Save Disk Space module helps you to save memory disk space by deleting the
unused iamges in the website.
For example, if a user creates a node with image attachment and later he/she deletes
the node, the attached image will still be maintained in the database with inactive
status as well as in the sites/default/files folder.
This module helps in listing the inactive images so that user can review and delete
the image to save memory space.
