Tungsten C Upgrade - Clean up question

I have just had my T|C returned from Palm with the MAC address fixed -
slightly surprised that the patch was not already installed.

I installed the patch OK - however, the hotsync reinstalled the six
files (or appears to) that were used for the installation.

Can I delete these, or should they remain? - I did delete the setup
file as indicated in the instructions - its the other 5 I was
wondering about.
