About the plugin

File Manager is a plugin adding new procedure blocks allowing you to create and read your files! Adding support for JSON files, it gives you the possibility to create a config file or files to save data for your mod. This plugin has also more usage, but this it to you to find them! :)

File Types

  • TXT Files:


In this example, each time a block is broken a new file named file.txt will be created at the current game's directory. Then, the procedure will read this same file and send a message to the player each line of the file. JSON Files:

  • JSON Files


This image shows an example of a small JSON file containing another JSON object with values and a value. The first (main) JSON object (shown by the "Write following values as a JSON file" block) contains everything the JSON file will have. Then, the sub JSON object will be created containing normal values. When the JSON object has been added into the file, the procedure will get the field named number into the JSON object subgson shown here by gson,subgson. To get a sub JSON object. you have to write every JSON objects in the order of the procedure and separte them with a comma (No space).

This seems really useful but it's unfortunately won't work for any recent versions. Could you make a version for 2021.1 EAP (03117)?

Very cool!! But is there a way to use itemstack in a json file?

Can anyone release a video explaining how to possibly make a config file with this? I am trying to make one but I seem to be failing at it. Thank you

I saw the second photo. I just don't understand how it works. I'm trying to make a config to where I can disable or enable my ores from spawning into the world kind of like how other mods work. So I can make them better compatible with each other.

can you post a video tutorial on this plugin please, i am create a config to my mod to save blocks rank
