That’s interesting. EagleFiler gets the title from the PDF metadata or from the filename (without the extension) if the PDF metadata is blank. So I guess your scanning software put the extension in the Title field.
Thanks, but it looks like your script wasn’t saved properly. It just says “This script contains uncompiled changes and cannot be run.”
You could also use the Filename to Title script to set the title to the filename (with the extension).
