This simple module will provide a way to alter all file download paths slighty to avoid some file caching systems to prevent blocking access to new file versions. This module will add a checkbox to file field configuration page.
Some aggressive file caching may cache files based on the filename, failing to refresh the file when it is being updated in Drupal filesystem. This may happen when users are allowed to overwrite existing files with new versions instead of adding new files with new names (new version of file.pdf becomes file_0.pdf).
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.
