There's
a known
issue in Drupal 8 that
sometimes prevents
unused
files from being
entirely
deleted.
This means that while the
file may have been
removed, references to the
file continue to
exist. This causes
those file references to
show over the API and,
therefore, show in your
FUSE content
visualizations.
If you continue to
see deleted files showing
up at the Drupal API
endpoint (and, therefore,
FUSE), try one of the
following methods to
remove
them:
Install and use the File Delete module.
Advanced users can remove the entries from the files_managed database table manually, using SQL or phpMyAdmin.
