dbx

There are two different softwares that use dbx extension: 

1- Outlook Express E-mail :
E mails that are taken by Outlook express kept in single file. This file generally may be like this: Inbox.dbx, SentItems.dbx or for the folders which you created may be like this : oldarchive.dbx

You can not interfere directly this file. However if you need to transfer the files between two computers it is just enough to copy it from the C:\Documents and Settings\kullanici\Application Data\Microsoft\Outlook folder and put it the same place

To data transfer between two different email softwares you may use File-import / File export option. Also, you can use Dbxtract for repairing corrupted dbx files.

2- Visual FoxPro table :The information tables that are created by database software called Foxpro also take dbx extension. You may use Microsoft Foxpro or Access software to run these files.
