it gives following 3 options
1. You can store a document against a DIR with the GOS icon instead of in the originals area (called Document Archiving)
2. You can check a document into the archive using the Original - Check into Archive menu path option. This is often used to remove documents from the content server after a period of time when they are no longer accessed. I.e. When a document gets to version 05, you may opt to archive version 00.
3. Data archiving - You can archive an entire DIR along with any originals
Thanks and regards
