If you have problems with individual steps, do not hesitate to ask specific questions.

I have *no* scripting experience whatsoever.
Would one of you be so kind as to write a script for me which downloads (to my pc) and deletes the content (from ftp) of the same folder every night?

huge thank you in advance!!!
