File type: Temporary file
A tof file extension identifies a temporary thumbnail file used by Presto! Mr. Photo.
These files are created for the software's internal use while it manages and displays photos.
File type category:
Temporary file
Date updated: October 30, 2026
The tof file extension is associated with Presto! Mr. Photo, a photo editing and management program for Microsoft Windows developed by NewSoft.
A tof file contains temporary thumbnail data for a photo. It is an internal working file rather than a user-created photo document and is used by Mr. Photo to display thumbnail previews.
Presto! Mr. Photo on Microsoft Windows uses tof files internally. They are not intended to be opened separately, and the software normally handles them automatically.
A tof file is a temporary thumbnail file, not a source image or a standard image document, so it cannot be meaningfully converted to another format. Use the original photo in Presto! Mr. Photo if an image export is required.
