Disk or folder can't be read
- Check whether the disk appears in Finder.
- Check its connection and cable.
- If Merceq can’t access a folder, use Add → Add folder to show it again with the macOS folder picker.
- If Try again is offered in the Import window, use it.
When you reconnect a disk, Merceq may detect the connection automatically. Check the “{disk} is back — {n} clips are reachable again.” message in Notifications → History. If the files haven’t been moved elsewhere, you don’t need to locate them separately.
An empty folder and an unreadable folder aren’t the same situation. Check the files inside the folder in Finder to see whether there really are videos there.
If files were moved elsewhere, you may need to show the new location with Find the videos instead of scanning the old source again.
