[xwiki-users] Link to a file in local file system

Hi, Isnt there a way to link to a file on the local file system? I tried using both the WYSIWYG editor and the creole syntax and both dont work. I know i can link to an attachment but thats not what i want. I want to add a hyperlink to a document that links to a file that is somewhere on the C: drive. Is this possible? Im using the latest version of xwiki downloaded yesterday. Thanks
