Parameters
Usage
To access a file on a remote system, the account (for Windows) or user (for UNIX and Linux) that
is running ColdFusion must have permission to access the file, directory, and remote system. For
example, if you run ColdFusion MX in the Server Configuration as a Windows service, by default
it runs under the local system account, which does not have sufficient privileges to access remote
systems. You can change this, however, on the Log On page of the Services Properties dialog box.

the correct file name, #GetFileFromPath("#thisPath#/#yourfile#")#
