= Handling Files Attached to Deleted Objects =

Two options when object with files is deleted:

 1. The files are also deleted
 1. The files are ''de-attached'' and placed in the unattached file list

There should also be separate buttons for deleting and de-attaching files from revisions and notes.

= Non-Delete Operations =

 1. Removing an item from a Dossier
 1. Removing an item from a unsent Transmittal
 1. Removing a link between items
