How is deleting a study or project different from archiving?

Deleting an archive file decreases the size of the database by removing unwanted studies, study projects, and library projects.

Before you delete a study, study project, or library project, Oracle recommends that you perform a full database backup. You can also archive the study or project.

When you download an archive file, you have the option of permanently deleting it from the database.

Note: You cannot delete or archive the System Library or its project.
