C:\Users\BosmanG\AppData\Roaming\EchoPAC\Export\Backup\resources\idunn\userdefs
However, whether or not a check mark is ticked at LA volume & RA Volume on the EchoPac plugin is placed in the following distinct location :
C:\Program Files\GE Healthcare\EchoPAC PC Plugin\User\target\resources\idunn\userdefs
It would be good if all EchoPac plugin settings are placed into the \AppData folder [not in \Program Files folder], since a new VDI session is offered to users every day, thus causing the settings under \Program Files to disappear at each new VDI session.
