Things You'll Need
Instructions
Connect the USB flash drive to either USB port on the front of the PS3. It doesn't matter if the PS3 is on or off when you do this.
Use the directional pad to scroll to the category (video, music or photo) on the XMB (the PS3's main menu) that best represents the type of media you want to put on the PS3. If you want to put videos on the PS3, you'd select the "video" category.
Use the directional pad to scroll down to "Memory Stick" and press the "X" button. Select "Highlight All" and press the "X" button. All of the files (for the category you selected) on the USB flash drive will be displayed.
Select the files you want to put on the PS3, press the "Triangle" button and select "Copy." After a few seconds, the file will be transferred to the PS3 hard drive.
