DBU format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). File extension, signature and file format must match; otherwise errors will occur when the file is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our analysis of the DBU files produces the following result:

Most of these files are 160 MB to 160 MB in size. Certain words are almost always found in the files, such as <!---------------------------MONOLIT REGULAR with RPG----------------------->, <?xml version='1.0' encoding="windows-1251"?>, <specific_character id="aes_Monolit_rpg" team_default = and <xml>. The following filename is common: gamedata.dbu.
• 7% of all DBU files are based on the zip format, so several files are compressed and saved in one DBU file. Such a ZIP file contains 4 to 26 files with names like BackupConfiguration.json, \AcquisitionType\AcquisitionTypes.s3db, \ImageManagement\GlobalConfiguration.s3db, \ImageManagement\Implants.s3db, \ImageManagement\Institutions.json, \QualityControl\ and \Site\.
