What is a TFF file?

TFF files mostly belong to MPQA Subjectivity Lexicon Tool. TFF files are not a single file type but a set of different text‐based data files used by distinct applications.
They may serve as:

• Sentiment lexicon files for use with the MPQA Subjectivity Lexicon Tool. These files list words and associated sentiment data. See the MPQA website for details.
• Label templates that use an XML structure. Such files are used in TFORMer systems (TFORMer3 and TFORMer Designer) to define label layouts.
• Defect data files produced by Tencor Surfscan equipment, holding scan results from a Tencor SFS 7000.
• RFID measurement data files created by systems like Tagformance and processed by Voyantic Tagformance tools.
• Definition text files with tab‐separated values for lexical resources; these are similar to files used in WordNet (WordNet).
• Text feature files (or Text Fragment Format files) that store segments of text and related metadata, commonly handled by a TFF Converter.
• Yamaha mixer files that keep mixer settings for devices such as the Yamaha TF-RACK; these are edited with tools like the Yamaha TF Series Editor (Yamaha).
• German bank transfer or CAD/CAM files used within systems like SAP ERP; these files may also appear in product environments related to Tebis CAD/CAM (SAP).

To view or work with a TFF file, start by opening it in a basic text editor. This may reveal whether the file uses plain text, XML formatting, or a more specialized structure.
Note: Always use the specific software associated with the file's source to make any changes or to properly interpret its data.
FilExt.com tip: The file’s functionality is defined by its originating tool.
