Editing Updating Media Indexes on Synology NAS (section)

=== Resolution ===

First try renaming the directory, e.g. `missing-photos` to `missing-photos-a`. Then refresh the view in '''Synology Photos'''. This usually works to force Synology Photos to recognize a missing directory's existence. 

If photos are still missing, re-index the photos directory: '''Synology Photos''' > '''Account''' > '''Settings''' > ''(choose between '''Personal''' or '''Shared''' tabs)'' > '''Indexing''' > click the '''Re-Index''' button. 

'''SP''' will display "indexing..." next to the button. Re-indexing may take a while. I have not found any articles describing a way to watch the progress of the indexing. The only indication that the process has completed is waiting for the "indexing..." message to go away.
