Why is there no “Rename” link in the zone list?
Renaming a zone file would require you to update all zone tags that point to that file. This could mean hundreds of pages that need to be modified. We do not recommend you change the name of zone files. If you forgot to add an extension for the file name when you created the zone file and want it treated as a WYSIWYG file, you can add the file name to your file modification settings.
