What is a .xer file?
File Extension Details
The XER file format is a proprietary file format used by Oracle Primavera P6, a high-performance project management software suite. It is primarily used for exporting and importing project data, including schedules, resource assignments, cost information, and work breakdown structures (WBS). Unlike XML, which is also supported by Primavera, XER is a text-based format that uses tab-separated values to represent complex relational database structures in a flat file. This format is essential for project planners and schedulers who need to share project schedules between different Primavera databases or with contractors and stakeholders. Because it contains sensitive project logic and constraints, it is the industry standard in construction, engineering, and energy sectors for project controls. It allows for the transfer of entire project portfolios or individual projects while maintaining the integrity of the scheduling logic, such as critical path method (CPM) calculations and predecessor-successor relationships. It is often preferred over other formats because of its compact size and speed when handling very large, complex project schedules with thousands of activities.
