JDR file format details:

If you know the file format, you can also find out how to open or edit the file. The file format can be deduced from the file extension and the signature.

An JDR file is mainly used by one program with a specific format. However, the following two file formats are common:

90% of all JDR files start with the magic bytes 1NAJ, which are always the first bytes of this file format. These are binary files, so they do not contain words or text. JDR files are between 73 MB and 160 MB in size. The file type is relatively new. Several words can almost always be found in the files, e.g. 1NAJ and admin. A usual file name is 00000000.jdr.
