Hi. It sure can archive/zip any file type, just have a look to settings, tab #3 "filename" : a default list of excluded extensions/types is set. These types have been excluded because generally size benefit is very poor with all listed file types. But, if you want to give a try, just remove "PDF" or any other extension from the list. Thanks for the review. Cheers
