Notes about the SOI 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 SOI file type is primarily associated with 'e.Spreadsheet' by Actuate Corporation. A set of tools that support the creation and deployment of data in a spreadsheet format. Actuate e.Spreadsheet technologies include e.Spreadsheet Designer, e.Spreadsheet Engine, e.Spreadsheet Option, and SmartSheet Security Option. Actuate iServer System options are separately licensed products.
