Extract text from backup or model files (NBD)
To convert NBD files to another format, you need Nero BackItUp or other Backup software.
To convert other file formats to the "Proprietary Backup Archive" file type, you need software like Nero BackItUp or a similar tool.
The .NBD file extension leads a double life in the digital ecosystem, presenting significant challenges for users attempting to open or convert it. Primarily, it functions as a proprietary Backup Archive generated by software like Nero BackItUp or NovaBACKUP. These files act as rigid, compressed containers for system snapshots, user settings, or hard drive data. A secondary but highly active use case is within the gaming community: .NBD files serve as 3D Model assets used by the MT Framework engine, developed by Capcom. Found in titles like Resident Evil and Devil May Cry, these files store complex mesh geometry, vertex weighting, rigging, and bone data.
The core disadvantage of both formats is strict proprietary lock-in. A backup .NBD file is completely useless without the exact version of the software that created it. It uses custom encryption and compression headers, meaning you cannot natively open it in standard archiving tools like WinRAR or 7-Zip. To successfully "convert" a backup, you must restore the archive through the original software to a local directory, and then manually re-archive the raw files into a standard, accessible format like ZIP or 7Z.
For game modders, the challenge lies in extracting 3D assets to modify characters or props. Modders frequently seek to convert these .NBD asset containers into editable, universal 3D formats like FBX or OBJ for use in specialized software like Blender or Autodesk Maya. Standard community workflows usually require custom Python scripts to parse the MT Framework headers.
Because these formats are either tightly encrypted or highly specialized, generic online converters universally fail to process them. convert.guru takes a realistic, pragmatic approach: just drag and drop your file to identify the exact format, view it, and convert it when possible. While we cannot magically bypass proprietary Nero encryption, our deep-scan analysis can inspect the file, detect the underlying hexadecimal headers, and show any embedded raw text strings. If our analysis detects a supported embedded format or an identifiable 3D mesh structure, partial viewing or conversion may still be possible.
Convert.Guru analyzes your NBD file, detects the exact format, and lets you read the text inside.
Users also converted NDB, NB7, TLS and ICA files.
If you want to convert NBD file to BAK, BACKUP, OLD, TMP, TEMP, ARC, ZIP, TAR, GZ, 7Z, RAR or ISO, you can use Nero BackItUp or similar software from the "Backup Archive & 3D Model" category. In the File menu, look for Save As… or Export….
To convert SNAPSHOT, OLD, IMG, RESTORE, ISO, COPY, VMDK, TMP, VHD, BAK, ARCHIVE or BACKUP files to NBD, try Nero BackItUp or another comparable tool in the "Backup Archive & 3D Model" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NBD converter.
