14 using your psa for mass storage
when you connect the player to your computer via the USB port, your computer will recognize your psa as a removable USB Mass Storage Device (MSD). The player is detected and automatically located as a folder named Removable Disk/ Device (e.g. D drive).
this means you can listen to your favorite music on the move and also use your psa to conveniently carry your work or data files such as Word documents, Powerpoint presentations, PDFs, etc.
once you have transferred the files to your computer, you can use normal file operations to e.g. copy, delete, rename your files.
IMPORTANT!
TO PREVENT FILE CORRUPTION OR LOSS OF DATA, PLEASE DO NOT REMOVE THE USB CABLE DURING USB OPERATION, FILE TRANSFER, FORMATTING OR WHEN UPGRADING IS IN PROGRESS.
ONLY UNPLUG YOUR PSA WHEN THE 
DISPLAY HAS STOPPED SCROLLING COMPLETELY.
