When you clear built, computed, and plotted data of model versions, or permanently delete model and file versions, Model Manager automatically detects and deletes unused data that may have been previously shared between versions via data deduplication. If the process is unexpectedly terminated while this cleanup is ongoing, for example if there is a power failure, that data will remain in the database until the next time you run such a maintenance operation. Right-click a database node in The Databases Tree and select Cleanup () to manually run the cleanup. This may take a few seconds up to several minutes depending on the size of the database.
