Notes about the FSS 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 FSS file type is primarily associated with 'File Split Pro'. File Split Pro is a program that allows you to split up large files into smaller segments. It also has support for registering itself as a Windows Explorer Extension to make Splitting files easier.
