Calling this function will release file handles internally cached by Unity. This allows modifying asset or meta files safely thus avoiding potential file sharing IO errors.
using System.IO; using UnityEditor; using UnityEngine;
public class AssetDatabaseExamples : MonoBehaviour { //Replace meta file information [MenuItem("AssetDatabase/ReleaseCachedFileHandlesExample")] public static void ReleaseCachedFileHandlesExample() { //Read and store meta information that will be replacing the meta file var metaContent = File.ReadAllText("NewMetaFile.txt");
//Get Material's meta file path var metaFilePath = AssetDatabase.GetTextMetaFilePathFromAssetPath("Assets/Material.mat");
//Release CachedFileHandles to avoid any I/O errors AssetDatabase.ReleaseCachedFileHandles();
//Replace the meta file with the contents of NewMetaFile.txt File.WriteAllText(metaFilePath, metaContent); AssetDatabase.Refresh(); } }
