What is a PTN file?
File created by PaperPort, a program used for scanning documents, organizing files, and sharing documents; contains data needed to display thumbnail images; serves as an index file for documents used in PaperPort.
Common PTN files are PPThumbs.ptn, which is used in most PaperPort versions, and PP11Thumbs.ptn, which is used in PaperPort 11. PaperPort is available in Standard, Professional, and Enterprise editions.
PTN files may be deleted, but they will be recreated the next time PaperPort is launched.
