Enter into the C drive and double click on the Program File’s folder.
A file by the name of Yahoo will be present there open it.
Double click on the Messenger icon and open the Prowp-content/uploads.
The Profile folder basically contains the complete Message Archive.
If you are intending to transfer the logs on a CD or a USB, then drag the icon of Profile onto the CD or Flash drive’s folder.
The other method is to copy past the entire archive on a word file, and email the word file on your personal id.
