Write / Read CSV file with / by Name

Hi all

I have a problem to create file name for my txt or csv file.

In this link we can lern haw to write and read data from file.

But I would like to create fith certain name.

I prepare IO fild with tag FileName [WString]

As in this link i would like do somethig like this:

path="\Storage Card USB\FileName.csv"

How can you write data to a file or read data from a file by means of a script on a Comfort Panel with SIMATIC WinCC (TIA Portal)?

Next question.

It is possible to prepare a field where i can find all my file.

I would like create a many file with data and call them by name.

Something like txt list. (but the list will be a names all file in certain folder).
