.txt into a char

[MiiNiPaa]

will the program wait for it to finish?

Yes

is it possible to target an upper folder?

You can get full path to current directory and extract parent one from it. Or just use special virtual ".." directory which means "parent directory"

Thank you so much, you have helped alot!

And a bit of a side question, can I make the program force restart after some time?

[MiiNiPaa]

Make another program which will restart first after period of time. Or just use your OS scheduler.
