What is a PTN file?

PTN files have multiple uses, and PaperPort Thumbnail Image is one of them. Read more about the other uses further down the page.

PaperPort Thumbnail Image

PaperPort is a document management software application by Nuance Communications. The PaperPort software is used to scan and organize documents and share the documents with other users via email or the Web.

The PTN files contain thumbnails for images used with the application. A thumbnail is a miniature version of an image shown on image selection screens. This speeds up the display of images a lot since the files are a lot smaller, and the program does not need to scale down the full-size images on the fly.

These files are usually named PPThumbs.ptn or P11Thumbs.ptn.
