If you want to use UNC naming, then the syntax is

\\ServerName\ShareName\SubFolder(s)OfShare...

In your case you would need to define the "megasystem" folder on the server as a share named "megasystem".

Or, you could use whatever share is mapped for your test drive F: e.g.

\\server\FDriveShareName\megasystem\reports

As an alternative, if you have unrestricted administrative access to the remote system, you could also use the built-in administrative shares for the root(s) of its drive(s). For example, the administrative share for C: on the remote system is C$. If the folder you want to access is on C: then you could do something like

\\server\c$\megasystem\reports
