BLU file format:

To view or edit BLU files you need to know the file format, because it determines how the data in this file is stored. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the BLU files:
