I have a question. I made a GUI which can store and load a .csv. Currently I can have only one .csv file with a fixed name. I want to work with a folder and several files instead.

Is it possible to do something similar in processing? (to work with OS windows)
Kind regards,
Bas

I use table = loadTable(“Infinity\_Report\_3\_31\_2021.csv”, “header”); Then I populate arrays with my data. I would like to browse inside the sketch to different files I want to open. Like you go in “word” and browse for files to open. Long term I would want to select a date range and open multiple files and see trends… Is this possible? Also I am trying to open a…

And for saving a file you can check the [Output \> Files](https://processing.org/reference#output-files) section of the Processing reference.
