All about TDR Files

The TDR file type is primarily associated with TINA.

TDR	File extension: TDR
	File type:	specialized data file

What is a TDR file?

TDR files mostly belong to TINA.

The TDR file extension is used by many unrelated applications. In one instance, it stores circuit simulation results from TINA, which many engineers use for testing and design.
Other uses include:

3D topography data: Files made by MountainsMap capture surface profiles for digital analysis. See also Digital Surf.
Device simulation: Some files use the HDF5 format to hold data from semiconductor simulation tools like Synopsys Sentaurus TCAD. More tools are available at HDFView.
Decision or roulette data: These files may store the outcomes or settings used in decision roulette applications.
Audio plugin presets: Certain TDR files hold preset information for plugins such as TDR Nova GE by Tokyo Dawn Records. More info can be found at Tokyo Dawn Records.
Genealogy records: TreeDraw uses TDR files to save data for family trees.
Time Domain Reflectometry (TDR) data: Some files contain measurement data from oscilloscopes (e.g. Tektronix instruments) for analyzing signal reflections. A related tool is the Tektronix TDMS Advanced Analysis Library available at Tektronix.
Cave survey data: Certain survey recordings for cave mapping are saved in TDR files, as used by Therion. Visit Therion for details.
Tencent records: A few instances involve game data or serialized records, for example from replays in games like Arena of Valor.

FilExt.com tips: Each TDR file carries specialized data that must be opened with the correct application. Identifying the file source is critical. For example, a TDR file from a circuit simulation is best read in TINA, while those using the HDF5 structure are viewed using HDFView. Always check for details in file properties to select the right viewer.

How to open a TDR file

You need a suitable software like TINA to open a TDR file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your TDR file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a TDR file directly in the browser:. Just drag the file onto this browser window and drop it.

TDR file format details:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the TDR files is as follows:

The TDR file ending includes different formats for the applicable programs. But the following two file formats are common:

20% of all TDR files use the same file format, which can be identified by the letters "OBSS" at the beginning. They consist of unreadable binary data. The file size is in the range of 6 KB to 2 MB. This file type is based on cutting-edge technology. The files contain the following words: B(c) Copyright 1993,94,95,96 DesignSoft Inc, OBSS, +Analysis result & diagram viewer settings, 02/09/96 17:00 CET, All rights reserved and TINA 9.3.200.277 SF-TI. Noname.tdr is a typical file name.
15% of all TDR files have the same signature 33 00 44 00 44 00 61 00 74. These files are binary files, so they do not contain text, but only cryptic characters. TDR files can be up to 29 MB in size, but are often around 770 KB - 5 MB. The following keywords are characteristic: 3DData. Files like these are sometimes connected to ddata.

All the rest of the TDR files (65%) have different formats, the following 9 formats can be found: Treebit Decision Roulette data, HDF5, TreeDraw, TDR and BETA. Tagged as compressed, nmos, limiter, media, share or orca. Drag & drop your file here to see the file format and a preview of your TDR file!

How to solve problems with TDR files

Associate the TDR file extension with the correct application.
Update your software that should actually open specialized data files. Because only the current version supports the latest TDR file format. Search, therefore, e.g. on the manufacturer website after an available TINA update.
To make sure that your TDR file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
