I have taken this advice. Files were scanned in as "CopierBrand_date.pdf" and this is what is shown in the bottom left of the viewer. I have created a simple workflow to concatenate four indexes into a field called "document name"and set this index as the "document name"in database fields. (field1_field2_field3_field4.pdf)
If I download one document, the new document name is the file name of the document (field1_field2_field3_field4.pdf), if I multi select, the files come down zipped and have the original file name of "CopierBrand_date.pdf"
Do you have any clues?
