KiraN,

>Is it the fact that VFS only exist on the card. 

Correct.  The VFS is only for memory cards (or an internal memory card volume
such as on the T5).  The RAM storage in a device does not support any file
system, including the Virtual File System.  Use must use the Data Manager.

Likewise, external memory cards do not support the Data Manager (calls beginning
with Dm...) but must be accessed via the VFS calls.

In addition, don't be confused by the fact the Dm...() calls take a "card
number" argument.  With the exception of the Handspring Visor line, I don't
believe any other device ever supported anything but 0 for this value.  It has
nothing to do with external memory cards.
