aqFileSystem to locate that a folder exists not working quite right

I'm using aqFileSystem to check that a folder exists but for some reason, the below script keeps hitting the 'else' statement even though when I debug 'sTestPath + where', the correct path is present AND that path does match what appears on the computer.

Additionally, is there a better way to remove a trailing backslash than aqString.Remove?  

Thank YOU,

Morgan

(where is a case statement but essentially a path)...

where := '\StdData\'+BaseName;

sTestPath := aqString.Remove(Project.Variables.TestPath, 8, 1); 

If aqFileSystem.Exists(sTestPath + where) then 
begin 
     Log.Message('ValidReports folder present')
end
else
begin
     BuiltIn.ShowMessage(Project.Variables.TestPath + where + ' folder is missing from the ValidReports folder!');
     Runner.Halt(Project.Variables.TestPath + where + ' folder is missing from the ValidReports folder!');
end;
