Notes about the ROOT 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 ROOT file type is primarily associated with 'ROOT' by Rene Brun & Fons Rademakers. The ROOT system provides a set of OO frameworks with all the functionality needed to handle and analyse large amounts of data in a very efficient way. Basically, a .ROOT file is any C++ object.
