Solved can't understand this condition: 'folder doesn't exists'

[Flajakay]

Sorry for my bad english, since it's not my native language. So i decided to create configs and language files for my script.

Spoiler: code

on load:
if folder "plugins/RaceS/" doesn't exists:
create folder "plugins/RaceS"
if folder "plugins/RaceS/Language" doesn't exists:
create folder "plugins/RaceS/Language"
if file "plugins/RaceS/Language/ru_RU.yml" doesn't exists:
create file "plugins/RaceS/Language/ru_RU.yml"

Then I fill these files such way:
wf "## Файл языка конфигурации RaceSystem" to "plugins/RaceS/Language/ru_RU.yml"
I'm doing everything right?

And so on.
I installed addons:
SqQuery.

You added an extra s, which yiu only need when it isn't negative
