[TYPO3-english] Enable browsing to a subfolder of Typo3 install?

[damien mesnager]

Hello everyone,
very new to Typo3 and kind of lost, i think it has to deal with realurl but i'm not even sure.
I have a website using typo3 in my root folder /www/
I need to install files that have nothing to do with typo3 in a subdirectory, say /www/new/, and be able to browse those files.
The problem is when i type h**p://mydomain/new/ i get a nice message from typo3 " Error! Reason: Segment "new" was not a keyword for a postVarSet as expected!"

Is there any simple way to bypass this behavior of Typo3 that will simply let me live my life with subfolders on my server ? :-)

thanks in advance for your help
