Understanding aging and archiving rules for items in a volume
You can set an expiration policy for a folder that affects all items in that folder. Alternatively, you can set the policy for an individual report.
An item ages and expires according to a set of rules you apply to the item itself, to the folder that contains it, or to the entire volume. The following aging and archiving rules apply to volume items:
*Volume archiving rules apply to every folder in the volume, including subfolders. By default, the production volume archives files and folders once a day. The system administrator can change this default setting to specify when and how often to archive files and folders.
*Folder archiving rules apply to the entire hierarchy of reports in the folder, unless subfolders also have age or date properties.
*Subfolder archiving rules supersede age or date properties of folders higher in the hierarchy.
*A rule for a file overrides a rule inherited from the folder that contains the file.
*Folder aging and archiving properties specify the file type to which those properties apply. You can specify file types explicitly or use default values.
*The aging process does not remove folders during archival, only their contents.
*Archive rules determine whether the system ages dependent files along with the original files.
