What is an NDB file?
The core fact is that an .NDB file is usually a database file. Many different software programs use this extension to store records, logs, or system data. A common format is an SQL application database managed by SQLite. Other software uses .NDB for access control databases, such as ZKTeco biometric devices. The extension also stores aviation and marine navigation data for Jeppesen and Navionics.
Alternative Uses
Because the .NDB extension is not standardized, it has multiple possible meanings. It is famously used as a ClamAV Extended Signature File created by Sourcefire to detect malicious software. Game engines, including the Ubisoft Nomad Engine and BioWare Neverwinter Nights, use .NDB files for compiled game scripts. Additionally, Nevron Software uses it for binary drawing documents, and the Noteshelf app uses standard ZIP compression to store notebook backups under the .NDB name.
How to open and convert NDB files
If you do not know which program created your file, do not guess. viewer.online/ndb analyzes .NDB files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If you need to extract the data, we recommend file conversion to sensible target formats like .CSV or .SQL on convert.guru.
Summary
In summary, because many .NDB files use the known SQL format, viewer.online/ndb can safely open and display them online, eliminating compatibility problems.
