User Profiles

Hi,

I would like help with a problem.
It’s more of a home pc problem really, i am running Windows ME with 2 users running their own profiles, each profile has their different settings when installing programs the 2 profiles can use this but they can also see files accosiated with a particular software.
I installed a mobile phone software on my profile but the other profile can also see the files i downloaded from my phone, i.e. contacts, photo’s
how can i stop this from happening?
can i restrict the profile in some way?
any suggestions would be greatly appreciated.
Nick
