Understanding Outlook Express Files
Sound prevention begins with sound understanding, so let's begin with a look at the Outlook Express user files. Each folder that you see in the Outlook Express Folder list is stored on your hard disk as a single file with the same name as the folder but with the extension DBX added at the end, such as "Inbox.dbx" and "Sent Items.dbx". All these DBX files are stored in a single Windows folder called, not surprisingly, the Store Folder. The Store Folder is usually located deep within the Documents and Settings folder in Windows 2000 and Windows XP, and is by default marked as a hidden folder. This makes it tricky to find your Store Folder in Windows Explorer, but there is a very good reason for this. One source of DBX corruption is trying to open and edit a DBX file yourself.
