Open TDF File

TDF extension files can acquire various formats, of which we are going to see some, below

Title Definition Format File

In this section, a TDF extension file contains setup instructions for backing up DVD movies.

The TDF file can be opened with various software packages such as DVD X, DVD-X Copy, DVD X Platinum, and DVD X Copy Express.

About DVD X

DVD X is a complete software package that allows novice computer users to copy any DVD movie to any blank DVD.

Most commercial DVD movies include Content Scrambling System, a copy protection technology designed to prevent DVD movies from being copied, however, this software has technology enabled to decrypt CSS protection.

Perhaps because of the above controversial feature, this software is no longer sold or supported, which means the developer's cessation of operations.

The TDF file can be used to modify and fix DVD authoring issues and incorrect title set selections made by DVD X software.

Guide Text Definition File

In this case, the TDF file contains the definitions of the data sets used by a Guide, a desktop planetarium and star mapping program.

The TDF can be included on the application CD or saved to your hard drive during program installation.

Text definition files can be modified in a text editor, such as NotePad++.

Xserve

In the latter case, the TDF file stores the test instructions and parameters for the system tests run by Xserve Remote Diagnostics.

Xserve Remote Diagnostics is an Apple Mac-enabled tool for running remote diagnostics and tests.

The TDF is used to test the performance of components on an Apple Xserve server computer and can also be edited in a text editor.
