NBF file format:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. Knowledge is power - this also applies when dealing with unknown or faulty files. Below is our analysis of the NBF files:

The NBF file extension is quite common and is used by different programs with different formats. But the following two file formats are common:

60% of all NBF files use ZIP compression, so multiple files are compressed and stored together in one NBF file. An NBF file can contain up to 1400 files (mostly 74 - 590). File names inside are always predefhiddenfolder, \predefhiddenfolder\ and \predefhiddenfolder\backup\. Tip: If you rename the file ending to .zip and then double-click it, you see the included files and images. NBF files are between 59 KB and 10 MB in size. The keywords predefhiddenfolder/predefisasettings/usersettings/user_settings.wbxml, predefgallery and predefthemes are typical for these files. Examples of file names are Backup000.NBF or Backup001.NBF. Files like these are about sicherung, loha, sauvegarde, kopia, seguranc, message and zapas.
5% of all NBF files have the same signature EB 52 90 4E 54 46 53 20 20 20 20. They consist of unreadable binary data. NBF files can be up to 12 GB in size, but are often around 270 MB - 1 GB. Several words can almost always be found in the files, e.g. NTFS and NTFSu. Some examples of file names are Complete System Backup_0_1.NBF. These files are often associated with complete and system.

All other NBF files (35%) have no consistent format, such as FILE. Often described as folder, back, original, auto, contacts, acer or font. Drag & drop your file here to see the file format and a preview of your NBF file!
