A DTF file can be opened by double clicking it, and Windows then chooses the correct application to open it. A PC must have the correct software, such as FileViewPro, to open the file.
A DTF file is a miscellaneous file that is associated with Solid Edge Document, Exchanger Header File, ICEM CAD Data, ACDSee Use Database and Lotus Domino Server Temporary Files (IBM). Software applications for opening a DTF file can be downloaded online from reputable and legitimate sites. If the file is opened by the wrong application, it's necessary to change the file association settings in the Windows registry.
