File Deletion: Check this box if you wish to delete all archived and inactivated files from the static HTMLSite folder.
Note: Make sure the export folder (HTMLSite) does not contain any non-ACM files. This function deletes any file that does not relate to the content intended for export.
Once this option is enabled, the next full site export process will delete the static files corresponding to the archived/in-activated page. The deletion is done within both the-server side html folders and the FTP folders. If the archived page is restored, or the in-activated page is re-activated, the next site export will restore the page(s).
Scroll to the top or bottom of the Export Manager page and click Save.
