You can add "File with name "Name" in directory "directory" exist?"
this would be useful for mod to check if file already exists if not then make one :)

Hello Goldorion, if this mod is working on a server in the first place, is there a way to only write on files located on servers ? (not on client side)

It works fine, when using the Mcreator 2020.5 Server/Client for test, but on my server (forge 1.15.2-31.2.47) i'll get:

←[m←[1;31m[17:02:07] [Server thread/FATAL] [
FORM]: Attempted to load class net/minecraft/client/Minecraft for invalid dist D

i guess, i'll need a different version of 1.15.2?

When I use 'Get directory' It returns a '.'
e.g. [Render thread/INFO] [STDOUT/]: [net.mcreator.aliveagain.procedures.LoadConfigProcedure:executeProcedure:36 .
(I'm using print)
or does this only work when exported?

It also works with the environment test. However, there is a problem when using it with a server from what some users said. The server bug will be fixed in the next update. However, I can’t see the problem as you cut the console log.

I worked exported, I'm currently forcing the directory path to the test environment
By the way, I'm using the client test and haven't launched a server yet
By, By the way, It's a great plugin

could you add a "check if file exist" blok? So i can create a config that does not change, but only gets created when i delete the actual config.json file?
