Hi there,

If you really wish to have the data stores in different/ separate text files, make sure that you have different filename to the filepath.

You may, for instance, differ the filename by appending the system time to your filename.

i.e. DATA_191055.txt

Hope this gives you a clue to your problem.

PS: A similar example of file logging attached

What I have done is added the date to a filename to give it a new name. That is if you create a new file once every day. If not, you can also add the time to it also.
