In Maria Roldan's recent book on PDI v8 she says...

We will create a folder in the same place where our Job is saved. For doing that, in the textbox next to the Folder name option, type ${Internal.Entry.Current.Directory}/SAMPLEFILES and click on OK.

However, on a mac, the job fails with these messages:
Could not create Folder [/Training/samplefiles]
FileSystemException: Could not create folder "file:///Training".

Without this macro, the folder is created in the PDI folder in my HOME.

To me this indicates that the macro is interpreted as a 'root folder' in the file system.

So what is the correct syntax?
