XF 1.5 Does deleting an Allowed Attachment File Extension affect existing attachments?


Active member
If it's desired not to allow future attachments with a given file extension, does deleting the Allowed Attachment File Extensions from Attachments affect existing attachments that have been previously uploaded (or any cache rebuilds, etc.) ?

Would like to preserve all existing attachments that have been uploaded to date, but remove an attachment type which is no longer efficient given better formats/methods now for future attachments from this point forward.

You can safely delete the extension and it will not effect existing attachments.
