About NS1 files
The .NS1 file extension is primarily used as a NetStumbler Scan File. NetStumbler is a legacy Windows application designed to detect 802.11a/b/g Wireless Local Area Networks (WLANs). The file contains detailed log data captured during a wireless scan, including MAC addresses, SSIDs, signal-to-noise ratios, and channels. Alternatively, a small percentage of .NS1 files are Nestopia Save State files generated by the open-source Nestopia NES emulator, representing a save state recorded in 'slot 1'.
Users typically need to convert .NS1 files because NetStumbler is heavily outdated. It has not received an update since 2004 and is practically unusable on modern operating systems like Windows 10 or Windows 11 without virtualization. Furthermore, the scan logs are often stored in a closed, proprietary format that is impossible to read in a standard text editor. For the emulator use case, Nestopia save states are volatile binary files strictly tied to the exact ROM hash and emulator version used to create them.
The best target formats for NetStumbler data are CSV or TXT for spreadsheet analysis, or KML to map the access points geographically in Google Earth. Because this file format is difficult to open or convert due to its proprietary nature, specialized parsers or the original software are usually required to correctly export the data. However, convert.guru can still identify the file format, inspect the file, and show text or internal content. Just drag and drop your file to see what it is and convert it if supported.
Convert.Guru analyzes your NS1 file, detects the exact format, and lets you read the text inside.
If you want to convert NS1 file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use NetStumbler or similar software from the "Wireless Network Data Logging" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to NS1, try NetStumbler or another comparable tool in the "Wireless Network Data Logging" category.
The NS1 Converter Story
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 NS1 converter.
