How to manage many level navigation before the main operation

I am designing web application which needs 4 levels to manage the flow charts which is the main purpose of the application . The structure is something like this:

Company names - folder

Component names - sub-folder

Group name - sub - sub - folder

List of flow charts

The problem is the user has to make 4 clicks to reach its main task how should the levels be grouped or restructured to make the process efficient
