File Lock

This module allows you to "lock" files so they cannot be deleted.

File Lock can be used to control two different problems:

1. Preventing deliberate deletion of files
2. Preventing accidental deletion of files caused by the behaviour of Drupal's core file field

File Lock is particularly useful when used with a media library setup, for example using the Media module.

Features

• "Update options" in file overview (for existing files)
• Lock selected files
• Unlock selected files
• Automatic file lock for new files
• All files
• by filename pattern
• by regular expression
• Selectable by operation:
• all -> all file_save actions
• file_insert -> file create actions (new files)
• file_update -> file update actions (existing files)
• Integration with Actions, allowing un/locking of files using Views Bulk Update/Admin Views

File Lock acts in the background, there is no UI which shows the files that are locked and which aren't. A workaround is use a view in media browser showing the file_usage.
