recently I bought an archos 70 color and with my great surprise there was not anymore the archos fusion feature that use all the external memory as internal.

this feature was present in the previous xenon c that now is partially damamged. archos does not give any support on this issue. is there any way to have this function with or without rooting?

without passing applications or application data to external sd memory it will run easily out of memory.
