TSF Directory
The TSF directory is the place where TSF's are stored in the directory.
This directory is part of the legacy from RadiMation.
When it was designed there was still the 8.3 file system. More information about the 8.3 file system you can find here
Because users wanted to use more then 8 characters to define there files names, RadiMation has create a tree type of structure to overcome this problem. These files names have got a different identifier (red. name) then the user has specified. Because the name is stored inside the file you can make the name as long as you like. Beware, this is not an invitation to hack the file in order to change the file name. You should do this inside RadiMation. The best way to look at TSF file structure is like a database. If you change a single file by hand, you are on your own, and the correct working of the software is no longer guaranteed.
