In eFileCabinet 2015 and later (Desktop/On-Premise only), you are able to remove a template from every drawer in a cabinet.  This can be helpful if you discover a mistake in a template that was mass-applied, or if you decide to change the structure of a template that was mass-applied.  

To Mass Remove a template, highlight a cabinet and click Mass Remove Templates on the Administration tab.

You will be prompted to choose what template you'd like to remove.  If you'd like to remove ALL folders that are part of the template (including the folders that contains files), you can change "Delete template structures with file:" dropdown box to Yes.  (Repeating: If you change that dropdown to yes, your files that were saved into the template structure will be deleted along with the folders.)

After you've selected the template to remove, click Remove and that template will be removed from all drawers in the selected cabinet.  You can still recover your deleted folders from the Deleted Items for the cabinet or drawer.
