Cannot write to file (possibly it is READ-ONLY or the disk is out of space or not ready)
What happened
You tried to save or save changes to a IBM® Notes® document or application, or to save an attached file, but you cannot save because you are out of disk space or you are using read-only media, such as a protected volume or a CD-ROM.
What you can do
Check both disk space and privileges on the volume storing the Notes® application you are using. If you see this message when working with a Notes® application stored on CD (while Notes® tries to update an index, for example), copy the Notes® application to a local disk, then try again.
