Report Persistence problems in Entegra SR22 Series Posted April 1 · Edited April 1 by Astur I tried all of that already, it doesn't work. But after hours playing with permissions, i can confirm that the folder its not read only as i thought, because when something is read only you should have a check mark instead. Meaningless: Read only: And the persistence files doesn't have the read only activated as you can see. Also, other airplanes with persistence like the TBM for example are working fine. I tried starting xplane as an administrator too, but it makes no difference.
