Viewing .dat files and logs

I am conducting an investigation on a individual that used SmartFTP to transfer files to a ftp site. Can some tell me how I can view or decipher the .dat files to get more information about their history or setup. I would also like to know where the ftp logs are stored.

Feel free to contact me off list or via private message if this won't help others.

Any help would be appreciated.
