Hi kumbsky,
CuteEditorFileStorageType is the global setting, you can set the dialog separate, like below(only for flash dialog)
Editor1.Setting["InsertFlash-CuteEditorFileStorageType"] = typeof(SqlFileStorage).AssemblyQualifiedName;
If you did not set the global setting, you should set the store path for the flash dialog above
Editor1.SetSecurityFlashGalleryPath("/");
Regards,
Ken
