How to select asset in Project Browser without loading Asset.

dummy.cs

// use to select asset at the Project Browser when you know path and asset 
// has no objects inside, e.g. AssetDatabase.LoadMainAssetAtPath() returns null
// path - relative to Project folder, e.g. Assets/StrangeFile.asset
public static void SelectNonObjectFile(string path)
{
	string guid = AssetDatabase.AssetPathToGUID(path);

	// in perfect world, all reflection should be cached (including method delegate)
	Type assetDatabaseType = typeof(AssetDatabase);
	MethodInfo mi = assetDatabaseType.GetMethod("GetInstanceIDFromGUID", BindingFlags.NonPublic | BindingFlags.Static);

	if (mi == null)
	{
		Debug.LogError("AssetDatabase.GetInstanceIDFromGUID() not found via reflection!");
		return;
	}

	int instanceId = (int)mi.Invoke(null, new object[]{ guid });
	Selection.activeInstanceID = instanceId;
}

Sometime we will cache averything... sometime...
Nice solution! =)
