After JRiver crashed with a memory allocation error, I decided to leave the card in the device for a direct USB sync instead of the card reader I always use. It recognized the misnamed files but still thinks they are ok with the bad name compared to the source. If they are still there when it finishes the sync, I will batch correct and resync to see what happens.
Added: Crashed again during sync process. A complete mess with duplicate files for each entry which was having two file extensions now showing Delete On Sync. Plenty of free memory and disk space on all JRiver storage devices.
