Hi Hans-Goran,

> What is .tdf file?

TDF-Files are ASCII-Files that describe user-defined datasets (e.g.
the format of the data, in which file the data are ...).

> When i try to do one in Wordpad and save it , it comes up like
> New.tdf.txt!!

That is Wordpad! It always appends ".TXT" to the filename. Just
rename it to "New.tdf".

Kind regards
