recover rtf file
My husband has been creating a list of his favorite songs for the last several days on an rtf document on his MacBookPro. TextEdit 1.9.
He wanted to email the list to someone and selected all, copied and went to paste it in an email and only one song was there.
He went back to the rtf and there was only the one song there. I wasn't there so I don't know what happened. I tried control z, but it was too late. The document had been opened and shut a few times. The icon for the file is on the desktop and it shows a whole list on the little icon.
Is there some way to recover all of the info that was on the rtf file? Any help would be greatly appreciated. Thanks.
MacBook Pro, OS X Mavericks (10.9.5)
