Hello,
According to your problem description, since you have reinstalled the system after formatting the computer, please understand the original data would be overwritten and I am afraid to say they might be irretrievable. I suggest you try the following software to see whether they could help to recover your data.
Power Data Recovery V4.6

Windows Data Recovery Software

It is recommended that you should backup necessary data before reinstalling the OS in case that we get some files currupt or damaged in the future, which will protect ourselves from losing important data. Should any loss or damage occur, you can simply refer to these pst files. Thanks for your time and understanding!
Andy
