Delete files from sourcefolders after writing and copying

Hi guys......

i have a workflow where i source .xls files out from 3 different folders  e.g. C:\\temp\\PA8\\Lists, C:\\temp\\PA9\\Lists, C:\\temp\\PA7\\Lists

and split them (about an specified attribute) into many .xls files into another folder

e.g C:\\temp\\PA8\\splits, C:\\temp\\PA9\\splits, C:\\temp\\PA9\\splits

and additionaly i copy the source files with the filecopy writer into another folder

e.g C:\\temp\\PA8\\done, C:\\temp\\PA9\\done, C:\\temp\\PA9\\done

all that is working well!!!

BUT i want to empty the source folder after this processing in the same workflow......is this possible.....i have tried the Custom transformer File Deleter but i didnt get it how it works....any solutions or workarounds?

Cheers and Greetz
