Ok then. I have only tried FTP and that worked well for me.
For my method:
1. Download FileZilla
2. Connect PS3 to PC via Ethernet
3. Open multiman on PS3 and FileZilla on PC
4. Transfer Files using method below
Once FileZilla is installed, turn on PS3 and launch Multiman>System Info to get your current local IP. Also while in Multiman make sure FTP Service is set to "auto". With Multiman running go to your PC and open Filezilla and click file>site manager>new site.
Name it anything and then put your local IP# into "host". Port is 21, login type is "anonymous" no login or password is needed. Go to transfer settings
and choose active limit 1 and click connect. You will see your PC folders/files on left side, PS3 will be on right. To put a game onto your PS3
simply open your "GAMES" folder(right side) and then locate the game on your PC (left side). Right click and choose "upload" and you will see the
transfer begin. If you prefer, you can simply drag and drop files back and forth as well. After the transfer completes make sure to "fix permissions"
of that specific game from your PS3.
(Thanks to Cyan, for GBATemp.net for this guide and joshleeman for the FTP method. Find their work here
. Note that this is in no way my work.)
