How to save to file and load SaveStateJSON using FileSystem?

Hello, I want to create system to save and load save from file using FileSystem.

1) Save. Save only works with direct Text or when I'm saving SaveStateJSON to plugin Text and when taking data from there. (There is all version in the .C3P file)

2) Load. Can't make it work. It's just don't read any of my saved files.

What I'm doing wrong?

My .C3P https://www.dropbox.com/scl/fi/ys9yhw6oe95bjnapweml4/Save-Load-to-File-02.c3p?rlkey=0gvxymlnl7rtf59wo5vnheet1&st=gni1bcnl&dl=0

Your event sheet has two mistakes:

1. By default local variables are reset every tick, so SaveText will get cleared while the picker dialog is open. You need to make SaveText static so it preserves its value, or make it a global variable. Then saving works providing you enable the action to set SaveText to SaveStateJSON.
2. Loading doesn't work because the open picker tag is the same as the save picker tag ("mysave"), so when opening a file it will also try to save to it. Use a different picker tag like "myload".

Thank you for explanation Ashley Now everything works like I imagined
