Encountered an interesting error today after move from CF8 to CF9
the following code produces a path for a directory in which you can use CFFILE actions
<cfset thisPath=ExpandPath("/")>
<cfset thisDirectory=GetDirectoryFromPath(thisPath)>
<cfset RootPath="#thisDirectory#">
However you need to output the rootPath to see if it contains an ending slash or not.
Example we had a data/files/ directory where we wanted to store uploads.
so outputing our RootPath + data/files/ used to give us
Ipaddress//production/CF/application/data/files/
but after the change to CF9 the root path contained its own ending slash so we ended up with
Ipaddress//production/CF/application//data/files/
Notice the extra slash before data. This makes renaming files or moving them impossible. So if your rename or delete isn’t working, try checking your path’s final character.
