This menu item is less important since there are better methods to convert a TEMES measurement. Namely, the Tellert import library TIL_TMS.DLL (e. g. Drag-and-drop the .TMS file in the Windows explorer onto the file "TMS2TXT.EXE" to obtain an Excel importable .TXT file in the same directory as the .TMS file). Or the TEMES menu item Tools → Convert Files → TEMES to DIAdem...
.TXT: Converts into a text file without timestamps.
.XY: Converts into x-y recorder format.
.BIN: Saves the raw measurement block.
