Notes about the FIS file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The FIS file type is primarily associated with 'Dynamite VSP' by 3am Solutions (UK) Limited. Dynamite VSP is a 3D visualisation tool designed specifically for civil engineers and transport infrastructure planners. It is compatible with both 3ds max and Autodesk VIZ.
