I downloaded Yahoo Emails and merge the outlook mails to window mails.I find
there are many duplicate mails in window mail.
At first I manaually delete the dupliates in window mail, It costed me a lot
of time and only delete little parts of duplicates.
Now I find in window explorer, these are files for the mails.
I think I might use a tool to remove duplicate files in 'window mail' folder
on window explorer.
Is it sage to do so.
