What's the fastest method to access files/folders with editor script?

schlista · August 4, 2026, 8:28pm

I’m having issues with performance using editor scripts to manage files & folders?

The performance is just so slow (usually). I need a fast way across windows, linux, and MacOS.

Any tips/help would be greatly appreciated.

Is it? Can you share more details?

I’m using regular io API operations and editor APIs like editor.create_directory().

Look at my file_helper.lua:

github.com/paweljarosz/editor-scripts-ui-collection

editor_scripts/helpers/file_helper.lua

main

---@class FileHelper
local M = {}

---@param path string|nil
---@return string
local function normalize_path(path)
	if not path or path == "" then
		return ""
	end
	if path:sub(1, 1) == "/" then
		return "." .. path
	end
	return path
end

---@param selection any
---@return table
local function normalize_selection(selection)
	if type(selection) == "table" then
		return selection

When creating Defold resource files, use editor.create_resources, especially multiple at once (e.g. like in my model_from_gltf)

As far as I see @Insality is doing the same:

github.com/Insality/druid

druid/editor_scripts/druid.editor_script

master

local assign_layers = require("druid.editor_scripts.assign_layers")
local create_druid_widget = require("druid.editor_scripts.create_druid_widget")
local create_druid_gui_script = require("druid.editor_scripts.create_druid_gui_script")
local create_druid_collection = require("druid.editor_scripts.create_druid_collection")
local druid_settings = require("druid.editor_scripts.druid_settings")

local M = {}

local DEFAULT_WIDGET_TEMPLATE_PATH = "/druid/templates/widget_full.lua.template"
local DEFAULT_GUI_SCRIPT_TEMPLATE_PATH = "/druid/templates/druid.gui_script.template"

---Define preferences schema
function M.get_prefs_schema()
	return {
		["druid.widget_template_path"] = editor.prefs.schema.string({
			default = DEFAULT_WIDGET_TEMPLATE_PATH,
			scope = editor.prefs.SCOPE.PROJECT
		}),
		["druid.gui_script_template_path"] = editor.prefs.schema.string({
			default = DEFAULT_GUI_SCRIPT_TEMPLATE_PATH,

So as simple as possible basic io operations, nothing fancy, and it works, at least on my machine, pretty well.
