The Suisse Army Knife for TopfieldTM Files and Drives
Installation
TFtool is designed as "portable App", that means, no installation is required.
Just extract the zip archive into an arbitrary folder. TFtool stores all settings,
additional tools and temporary files beneath this folder.
Hence I recommend, not to extract into "Programs (x86)" directory of Windows.
Manual
Unfortunately the TFtool manual is outdated, perhaps it helps anyway.
