What is an FDS file?
The .FDS file extension is used by many different software applications. Because there are so many formats, a single .FDS file might be a Famicom Disk System image for retro Nintendo games, an input file for the Fire Dynamics Simulator, or a data file from a Hitachi spectrophotometer. It can also be an FME Custom Format File developed by Safe Software, or an ophthalmic scan from Topcon Corporation.
How to open FDS files?
Opening an .FDS file depends on its actual contents. If it is a retro game ROM, you can use an emulator like FCEUX. If it is an FME Custom Format File, you need data integration software from Safe Software. Medical and scientific .FDS files require specific proprietary tools like Topcon IMAGEnet 6. Because it is difficult to know the exact format, you must first identify the file structure.
