Currently I put my pst file (desktop) on a usb disk and then load it
to my laptop and work on it. Later I reverse the process, like at the
end of the day when I want to put it back on the desktop with updates.

Question: Is this dangerous/risky or would it be better to use a
synching program to sychronize pst changes from laptop to/from
desktop?

I've had no problems yet but I am wondering am I taking any risk, and
since I have seen a lot of synching programs (indicating that pst
download/upload is not too popular) maybe I am doing it wrong.

Thanks
