Hi @Anonymous ,
Thanks for posting your query on MS Q&A portal.
You can try concatenate the whole folder path in the derived column transformation where you are forming the file name, like below -
@markus.bohland@hotmail.de ('qatemp/',$detination,'/',<filenamelogic>)
this should derive to a string with the whole folderpath plus filename.
Please try this and let us know how it goes.
thanks
