Use the Data Lifecycle reports to view and export details of space used by inactive files and directories stored on configured file servers or SharePoint Web applications for the selected time period.

The elapsed time since the file or directory was last accessed or created.
The file server and the share name on which the file is stored, or the Web application and the site collection on which the file is stored
The file path.
The space, in MBs, used by the file.
The date on which it was last accessed.
The name of the user and user account that last accessed the file or directory.
The name of the business unit to which the user belongs.
The name of the owner of the business unit.
