Bill981 is right, you should be able to save it to the simpler file name with no problem. We use it to download several news, weather, financials, and sports programs each day and save them to a cart number in their respective folders where the automation can grab them.
For files from the sender with different file names each day that increment with the day, that too is pretty easy once you get the hang of their macros. All of our downloads do that, and spider handles them without any problems for going on 3 years now. However the filename you gave as an example has the word "and" and two dates in it. THAT will be a problem! Dont think you can macro that mess, might need to manually download.
Re support, yes it was sketchy at best from the DJB guy and pretty slow with the new bunch. For anybody using the older v 10.1.1 I stongly suggest you NOT upgrade to v 12.7. There is a bug that they admit they currently have no fix for. Other than some different screen graphics, and of the course the bug, I didnt see any significant changes in v 12.7, wish I had never upgraded.
