When you add a graphic object as a Composite Genie on a page, a Composite Genie instance that is uniquely identified by its presentation options, is automatically created in the project folder. This establishes a reference from the graphic object to this Composite Genie instance. There can be multiple graphic objects that refer to the same instance of a Composite Genie if their presentation options are the same. Therefore, deleting a graphic object does not delete the associated Composite Genie instance.
Over time there can be a number of Composite Genie instances that are not associated with any graphic object. These unused Composite Genie instances can slow down operations and occupy project disk space. You can use the Pack Libraries option to remove unused instances.
Note: You should not modify the properties of the folder in which Composite Genie instances are stored (\ProgramData\Schneider Electric\Citect SCADA 2018\User\<Project Name>\_CompositionCaches). You should not manually delete or modify files in this folder. Doing so may either prevent your pages from opening or cause your Composite Genies to be displayed incorrectly.
