Download Portal Sources *.ear in NW 7.3

Hello,

There is a portal project (NW 7.3) already deployed and I want to download it with sources.

How can I do it?

With NW 7.0 I have done it always with "System Administration->..." (par files) but I cannot do it in NW 7.3

and I cannot find this *.ear file with search in portal folders.

Regards,

Vladislav
