Click the File > Cleanup Tools > Archive.
Click the Archive this folder and all subfolders option, and then click the folder that you want to archive. Any subfolder of the folder you select is included in this manual archive.
Under Archive items older than, enter a date.
If you do not want to use the default file or location, under Archive file, click Browse to specify a new file or location. Browse to find the file that you want, or enter the file name, then click OK. The destination file location appears in the Archive file box.
Select the Include items with “Do not AutoArchive” checked check box to include any items that might be individually marked to be excluded from automatic archiving. This option does not remove that exclusion from these items, but instead ignores the Do not AutoArchive check box for this archive only.

Click the File >Click Options.
On the Advanced tab, under AutoArchive, click AutoArchive Settings.
