Thank you Naomi,

But my concern was more on files that would be used be a program later. Thinking again I believe now, that I should no care about it. Whoever puts files in TEMP must be aware that these files can be gone after the program was closed.

So I will set up a process that deletes files in a defined interval from the TEMP dir.
