+ * When reading resources, we need to avoid accessing temporary files

+ * or we might detect the file just before it is removed, leading to
+ * race conditions and errors.
+ *
+ * Unfortunately, QSaveFile doesn't provide a way to retrieve the

+ * file name it uses. By default, QSaveFile appends a `.XXXXXX` suffix
+ * to the original file name, where the `XXXXXX` part is dynamically
+ * generated to ensure uniqueness.
+ *
+ * This class acts like a lock by adding and removing the target file
+ * name into/from a global string set, helping to manage access to
+ * files during critical operations.
+ *
+ * Note: Please do not use the `setFileName` function directly, as it
+ * is not virtual and cannot be overridden.
