Convert Digsilent 2017 files to 15.1 version

[ortsas]

Hello experts*

Anyone knows how to convert Digsilent 2017 files to older version? Namely 15.1?
I have a client who gave me Digsilent 2017 files and I cannot open them in my older Digsilent.

There used to be a save to older version feature but the client said now it is not possible.

Any workaround? You could save me here

Thank you very much in advance.

You can ask DIgSILENT to do it.
They converted one for me when I asked them.

You can export from DPF 2017 to version 15.2
