Server File Paths with CFFILE

With Cold Fusion, in order to upload files like pictures to a server with the CFFILE tag, you have to have the absolute file path on the server (ie. C:\cfusionmx\wwwroot\blah\blah\blah\images\picture.jpg)

Is there anyway to find this file path out? I’ve come across it once a long time ago by luck inside of an error message, but can’t find it again.

This is an example of the tag incase it helps anyone answer the question:
<cffile action=“UPLOAD” filefield=“file_path” destination=“C:\cfusionmx\wwwroot\blah\blah\blah\images\picture.jpg” nameconflict=“MAKEUNIQUE”>

Please help if you can!.

Thanks
