I use the following two functions to load or save a string as a text file:

function save(path, filename, content) {
 try {
 java.io.File(path).mkdirs();
 var newFile = new java.io.File(path, filename);
 newFile.createNewFile();
 var outWrite = new java.io.OutputStreamWriter(new java.io.FileOutputStream(newFile));
 outWrite.append(content);
 outWrite.close();
 } catch(err) {
 clientMessage(err);
 }
}

function load(path, filename) {
 var content = "";
 if (java.io.File(path + filename).exists()) {
 var file = new java.io.File(path + filename),
 fos = new java.io.FileInputStream(file),
 str = new java.lang.StringBuilder(),
 ch;
 while ((ch = fos.read()) != -1) {str.append(java.lang.Character(ch)); }
 content = String(str.toString());
 fos.close();
 }
 return content;
}

the path of the current world is:

var path = android.os.Environment.getExternalStorageDirectory().getPath() + "/games/com.mojang/minecraftWorlds/" + Level.getWorldDir() + "/"

Excuse me I forgot to add a "/" at the end of the path and because of that the load function wouldn't find the file

to save a string

save(path, "filename.txt", "text to be saved in the text file")

to load a string

textStringFromFile = load(path, "filename.txt")

I made a smal example script to demonstrate the save and load function:

//define some variables
var X;
var Y;
var Z;
var path;

//save world path when opening a new world
function newLevel() {
 path = android.os.Environment.getExternalStorageDirectory().getPath() + "/games/com.mojang/minecraftWorlds/" + Level.getWorldDir() + "/";
}

function procCmd(cmd) {
 if (cmd === "save") {

 //save some numbers in the variables
 X = Math.floor(Player.getX());
 Y = Math.floor(Player.getY());
 Z = Math.floor(Player.getZ());
 
 //save the variables in the text file "position.txt"
 //note that the different variables are separated with semicolon
 save(path, "position.txt", X + ";" + Y + ";" + Z);
 clientMessage("position saved");

 } else if (cmd === "load") {
 //load the text file "position.txt" and save the string in the variable content
 var content = load(path, "position.txt");
 
 //split content by semicolon and save the loaded stuff to the variables
 X = content.split(";")[0];
 Y = content.split(";")[1];
 Z = content.split(";")[2];
 clientMessage("X " + X + " / Y " + Y + " / Z " + Z)
 }
}

function save(path, filename, content) {
 try {
 java.io.File(path).mkdirs();
 var newFile = new java.io.File(path, filename);
 newFile.createNewFile();
 var outWrite = new java.io.OutputStreamWriter(new java.io.FileOutputStream(newFile));
 outWrite.append(content);
 outWrite.close();
 } catch(err) {
 clientMessage(err);
 }
}

function load(path, filename) {
 var content = "";
 if (java.io.File(path + filename).exists()) {
 var file = new java.io.File(path + filename),
 fos = new java.io.FileInputStream(file),
 str = new java.lang.StringBuilder(),
 ch;
 while ((ch = fos.read()) != -1) {str.append(java.lang.Character(ch)); }
 content = String(str.toString());
 fos.close();
 }
 return content;
}

to test the example import it in BlockLauncher enter a world and use the command '/save' to save the current position in a text file. after that you can use the command '/load' to load the position saved previously

I hope this answers your question 1 and 2

Thanks helped a lot <3

the path of the current world is:

what If I want to save my mod menu and when you open BlockLuncher everthing that has been done is saved as it was when you closed blockluncher
