In the last blog post I talked about what an MDC file is. In this post I'll talk about it's companion(s) the .DB files.
The .DB files are shown in the screenshot below:
These are the content of your archive. They can be built on the server and downloaded (using BITS all controlled by the Enterprise Vault Outlook Add-in), or can be populated pre-emptively by the Vault Cache trawler. You get a variable number of these, depending on how much space you want to give over to Vault Cache.
With Outlook closed if you take a copy of one of these, and rename it to PST and attach it to Outlook, you'll see this:
Here you can see that the structure is also different - it does not follow the folder structure of your archive like the MDC file does. The structure is based on the date the item was archived. Whilst you can't see it in this screenshot the items here are the full items, attachments included.
