I don't think so.

I copied them off the device (I created a tar file on a memory card in the 
external slot and then copied the tar file off and saved it on my desktop 
system).

What I did was repartition the internal card, leaving the first partition as 
FAT32.  In my case I created two additional ext2 partitions but you can do 
anything you like with the rest of the space.  I used the built in utility to 
create a swap file on the FAT32 partition.

I left it there.  The GUI sees the (now smaller) vfat partition as 
the "internal memory card".  I have added /etc/fstab entries as needed for my 
extra partitions.

By the way, I have done the same sort of thing with the external memory card I 
use in the device: I have setup the first partition as VFAT, so the device 
can access it as normal, and I have other partitions for other purposes which 
I mount as necessary.
