Notes about the XER file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The XER file type is primarily associated with 'Primavera Project Management' by Primavera Systems, Inc. In Primavera’s Project Management module, you can exchange project data with other Primavera users by converting projects to Primavera’s Proprietary Exchange Format ( .XER ). Using Primavera’s import/export capability, you can then convert a XER file to an SDEF data file, and vice versa.
