The Inter@ctive Pager Backup (IPD) is a legacy proprietary file format developed by Research In Motion (RIM) specifically for early BlackBerry handheld devices. It was utilized extensively by the BlackBerry Desktop Manager software to store comprehensive user data backups, encompassing contacts, SMS messages, calendars, and internal database configurations. Although now obsolete and largely superseded by the newer BBB format, these files remain technically significant for digital forensics and historical data recovery operations.
