this would not greatly add to security but it would be addeded layer. all the archives have a magic header that will 
allow them to be scanned and identified, this is how it works on unix. maybe some thing of that sort is required....

even then how would it solve the prob of encrypted attachments. most archirve formats have an options where the file 
names are visible but some like rar have a option to encrypt file name also ie you cannot see the names of the files in 
the archive untill you have the password..
