i'm surprise to see i can delete a files like :

Blazer cache
datebk2HDB
HStracedatabase
HStracedatabaseHead
Kbdlayout_FR
memo38DB
... etc

I think in a first time treo read the ROM
and the Apps expand all need files also
after your setup preferences.
When you will need to change your battery
the ram will be entirely lost and your Device
will not be to return to customer service.

If a files is accidentally delete, you can
restore from a backup or what do you think
about the next run of this apps

I'm interesting to know how Treo work, is it
strictly like a PC or what is a mecanism differ
from.

Many thanks for comments
