Folders in PS3

[VorpalMonkey]

Is it possible to create a folder on the PS3's HDD? By that I mean under music, can I sort my songs into different folders if I want rather than just having them in one big list. Thanks

Doesn't look like this is an option right now. I have not loaded YDL 5.0 on my PS3 yet but this may be possible. I scanned my network'd ps3 from my PC for open ports and got nothing. It would be nice to be able to hyperterminal or telnet into the ps3 but I doubt this is an option.
