Explanation

DBX is the proprietary file format used by Microsoft Outlook Express to store email messages, folders, and account settings. Each DBX file corresponds to a mail folder (e.g., Inbox.dbx, Sent Items.dbx). Microsoft Outlook uses PST/OST files. Mozilla Thunderbird uses MBOX format. Eudora uses MBX format. Since DBX files are native to Outlook Express, it is the correct tool for forensic analysis of this file type. Forensic investigators encountering DBX files can infer the system used Outlook Express, which was bundled with Windows XP and earlier versions.
