Check if the ini path exists

[Aerocatia]

Do we want to do this? Currently it works exactly like the -path argument in that the directory will be created if it does not exist.

I found that if the parent folder doesn't exist, the game just crashes. Should I change it to check only the parent directory or just close this PR?

Edit: I will add a description next time, sorry! 😓

We should handle that somehow. Does this issue affect the -path argument too?

[MangoFizz]

Trying that on a fresh install of the game, it seems to be handled by stock strings.dll

[Aerocatia]

It probably makes sense to handle it the same way.

Great! I'll work on it tomorrow
