Your only option is entering the IP address of your PS3 and then starting the scan.
Note: You must have the PS3 FTP Server running before you start the program.
The program will scan the internal hard drive as well as ALL attached USB hard drives
When it finds a game it copies the PARAM.sfo file and the ICON0.txt file locally to your machine. When all games have been found it parses the PARAM.sfo, creates a txt file of the PARAM.sfo values named Title_ID.txt, renames the PARAM file to TitleID_Drive_PARAM.sfo and the ICON0 file to TitleID_Drive_ICON0.png.
The programs not perfect but most of the issue occur because the PS3 FTP server isn't stable. I still have to do quite a bit with error trapping, reading local drives...
