The .TAF file format is a proprietary format created by Toshiba and is used in a range of their products. The format is compressed, allowing more data to be stored. The file is used as a container file, meaning it may contain many different types of files. We have noted that .TAF files are mainly used by Toshiba for restoring operating systems (system restore) on their computers (disk images) and for storing digital media files (mp3s/images etc). You will need to use the software bundled with your Toshiba products to use these files.
