Just for your info, the file "folders.dbx" in the user's "Store Folder" maps the actual folders visible in Outlook Express to the DBX files that hold the messages for each of those folders. Folders.dbx is automatically regenerated by OE if it is deleted, which is sometimes used as a fix for a corrupt folders.dbx file.
Each of the DBX database files represents a separate folder or sub-folder and contains all the messages in that folder.
DBX Files can be opened using OE-Mail Recovery utility
http://www.oemailrecovery.com/outlook-express-recovery.htmlIt is a standalone program that opens the DBX file in a rough approximation of the OE message view and allows you to open emails, save attachments, and save out as many messages as you want to the *.eml format used by OE. You can drag and drop *.eml files from a folder into a newly created folder in OE again and they are then embedded into the DBX file created for your new folder.
You should be aware that the "Deleted Items.dbx" file normally still retains all deleted messages UNTIL it is "compacted". OE is set to prompt the user to compact database folders on the 100th time it is closed. The folder that was deleted from within OE may still be inside "Deleted Items.dbx", but probably only viewable as separate messages rather than as a separate folder containing messages, so your best bet is the DBX file you backed up.
Please also be aware that copying a DBX file from the Read-Only medium of a CD into the user's Message Store folder may issue errors when OE is opened. The Read-Only attribute has to be removed from the DBX files in the Store Folder.
To ascertain the User's Store Folder you open OE and use the Tools > Options > Maintenance tab, and click on the "Store Folder" button. It is set in the "Store Root" (REG_EXPAND_SZ) Value in the registry key:
HKEY_CURRENT_USER\Identities\{GUID}\Software\Microsoft\Outlook Express\5.0
