If the file is uploaded to our server, the downloaded file name will match either your original, as-uploaded file name, or the product's Item Name, whichever is shorter.
If the file is a Remotely Hosted file, the file name at the end of your Remote Product File URL will be retained as-is for the buyer's download. For example if the location ends with product1.pdf, it would produce a file with the name product1.
If the file name has any spaces or symbols that are forbidden in file names on any platform ( \ / ? & * | : < > ' ; ), those will be replaced by an underscore ( _ ) in the downloaded file name, and all letters will be normalized to all-lowercase, so a file upload originally named Mom&Dad's Recipes v1.0.pdf will become mom_dad_s_recipes_v1.0.pdf when the buyer downloads their copy.
