Search function in WinSCP script

Hi all,

at the moment I am creating a script where WinSCP is opening and searching for specific file types on a CNC-Machine via FTP (*.prt). The problem on this case is, the .prt files are always located in different folders and also the folders change (different names, etc.). So this is my current script:
This works fine, but the get command only looks for *.prt files in the root area and not in the folders that are located here. I also cannot define any folders and as they change multiple times daily.

So basicly I tried it with filemask, but filemask copy the whole folder structure and not the single files to my destination
