Bulk Delete is a feature in Admin Toolbox for Jira which supports a multiple deletion of Jira items, e.g. Issue type schemes or inactive workflows. This tool for Jira admins can be used for a more efficient and fluent workflow within Jira.
By now, the bulk delete operation just works for unused (e.g. unused field configurations) or inactive (e.g. inactive workflows) items in Jira, and makes sure that all unnecessary ones can be removed at a time.
