There was an old thread handling this
https://yabb.jriver.com/interact/index.php?topic=111833.0you need something like this in the search bar, from a view that lists all of your audio...
[=ismissing([filename])]=1Is this still valid ? In a view showing 1185 mp4 and mov files, there are some with no thumbnail. 'Locate on disk (external)' reports that the file does not exist. What can be confirmed with explorer.
When entering '=ismissing([filename])]=1' in the search bar, there were
no search results.
In a view with audio files I thought it would work. I noticed heavy drive activities when applying this search option. But when testing with renaming a file with explorer, it still does not get listed. Trying to play then reports 'missing'.
My media are stored on network drive. Audio files are referenced by a drive letter. Videos by UNC path.
