Loading the databases from previous installation mysql
Based on your question, I will assume you know the old data root in Program Files MySQL. If you simply copy the entire thing into the data root of your new MySQL 5.6, and then restart, you should be good to go. The .myi .myd and .frm files are the key parts as I understand it.

If you are unsure where the new data root is, check your new installation's my.ini file.
