Hi I want to utilise the file adaptor to pick up some PDF documents however I must not delete the source files from the server. I can see that there is a setting in the FTP adaptor to not delete from server but not in the file adaptor. Is there an easy way to do this or do I just need to create a custom adaptor that copies the files to a working location and records in a tracking global when I have done this so that I don't process the same file twice?
