InvaderX :
If you used a form to ask for a folder path, use the expression NodeWebkit.ChosenPath & "YOUSHOULDNTHAVEDONETHAT.txt" just after
If you used a form to ask for a file saving, I guess you should use the expression NodeWebkit.ChosenPath just after
NodeWebkit.AppFolder & "YOUSHOULDNTHAVEDONETHAT.txt" should create the file in the same directory as the application
I didn't used it myself though
If you want to create a file from a game, it should be in the users documents (or a subfolder), or in the application folder (or subfolders), If the file can be created somewhere else, I think you may ask the user where, Games don't really need to create files outside these boundaries in general
