What is the TDP file format?
A file with the .TDP extension is a file known as Sherif DrawPlus Thumbnail. This format is associated with Serif Europe Ltd..
The reliable way to open a .TDP file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .TDP files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
