I have a program that can find duplicate files. What my questions is if I get an email from someone and then I forward it to someone now I have a duplicate one in my inbox and another in my sent. If I delete the one in my sent then when I open it the attachment will not show. Is there a way for it to just store the file once and then create an alias pointing to the main file. Another example: If I attach a photo from iPhoto to an email there again is another duplicate. I would much rather Mail send the photo and create an alias to the original photo in iPhoto thus creating no duplicates. I hope that was not confusing. I want a program that will find duplicates and then keep 1 and create alias's for the one's deleted. I know this is not all cases of duplicate files but mainly my Mail has way to many duplicates. Thanks for any help. I am using File Buddy 9 to find duplicate and empty files or folders. Also is it bad to delete empty files? There are tons in the system folder.
