.gitignore Ignore everything except individual files

Question

git

For some reason, it is not possible to make the folder and its contents visible

# сначала все в игнор
*

# исключить из игнора файлик
!file.txt

# исключить из игнора папку с содержимым
!folder/*

Everything is ok with the file - it is visible! And the folder is still ignored. How to make a folder and its contents visible?

Answer 1

/*
!file.txt
!/folder/

Answer 2

Try removing the asterisk after /

Answer 3

if your files are on the path /a/b/c/d/*
you need to write like this:
*
!a
!a/b
!a/b/c
!a/b/c/d
!a/b/c/d/ *
