A .tdt file is a data container that serves different purposes depending on the device that created it. Most frequently (79%), it is a PVR Thumbnail generated by Topfield digital video recorders to display preview images of recorded TV shows. While these files are internally standard JFIF or JPEG images, their non-standard extension prevents them from opening in default viewers like Microsoft Photos or Apple Preview. Users often need to convert these to JPG or PNG to archive recordings or manage media libraries on a PC.
In scientific and medical contexts, a .tdt file is often a Tab-Delimited EEG data log exported by Cadwell monitoring systems (e.g., Easy III). These files contain raw neurological waveform data in a text format that is difficult to interpret visually. To analyze this data, researchers must convert the file to CSV, XLSX, or PDF, making it accessible in spreadsheet software like Microsoft Excel. Less commonly, these files may be Enigma Virtual Box packages used to virtualize application files, which are strictly for software execution and rarely converted.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our TDT converter.
