in this file: src/controllers/uploads.js:154

uploadsController.uploadFile = async function (uid, uploadedFile) {
	if (plugins.hooks.hasListeners('filter:uploadFile')) {
		return await plugins.hooks.fire('filter:uploadFile', {
			file: uploadedFile,
			uid: uid,
			folder: 'files',
		});
	}

	if (!uploadedFile) {
		throw new Error('[[error:invalid-file]]');
	}
	const isAdmin = await user.isAdministrator(uid);
	if (!isAdmin && uploadedFile.size > meta.config.maximumFileSize * 1024) {
		throw new Error(`[[error:file-too-big, ${meta.config.maximumFileSize}]]`);
	}

	const allowed = file.allowedExtensions();

	const extension = path.extname(uploadedFile.name).toLowerCase();
	if (allowed.length > 0 && (!extension || extension === '.' || !allowed.includes(extension))) {
		throw new Error(`[[error:invalid-file-type, ${allowed.join(', ')}]]`);
	}

	const currentDate = new Date();
        const year = currentDate.getFullYear() + '';
        const month = String(currentDate.getMonth() + 1).padStart(2, '0') + '';
        const date = String(currentDate.getDate()).padStart(2, '0') + '';
        const random = Math.random().toString(36).substring(2, 4);
        const dirPath = path.join('files', year, month, date, random);
        
        return await saveFileToLocal(uid, dirPath, uploadedFile);
};

i thinks this is good for files manager
