Hello, I just XOGged out an inactive project, then set it to "to delete" in the application and XOGged it out again. The difference between the 2 XML files was that the project had closed="true" in the XML (for the one with purge_flag set) and ="false" for the un-deleted one. HOWEVER, I tried XOGing the closed="true" file back into the application and it did NOT update the purge_flag? So perhaps it is not supported? (This was in 8.1 FP03)
