What is a NEO file?

NEO files mostly belong to Neo-Geo Emulator.

NEO files serve different specialized purposes. The most common use is as a NeoGeo ROM file, which stores game code and data for SNK systems. They are used with emulators that run Neo-Geo games.

Other uses include:

Radio Scanner Data Files: These files keep channel settings and configuration data for radio systems. They are handled by programs like RSI NEO Editor and supported by tools such as Radio Mobile. For more details, visit Radio Mobile.
Neo4j Database Files: In some cases, NEO files contain graph database or neural network data. Programs like NeoOffice or NeuroExplorer are used to open them. Further information is available at NeoOffice.

FilExt.com note: Since the extension is shared across different applications, it is important to use the proper software based on the file's origin.
