First you need to know the name of the directory you want to download. The directory names are the last part of the DOI or the DOI Link of the dataset. You can find both in the description of the dataset.

For example, the dataset "OLANA MRI YNH" has the DOI doi:10.57782/RZM27T and the doi resolver link doi.org/10.57782/RZM27T . Therefore, the dataset can be found in the directory RZM27T.

Install FileZilla if necessary. Start FileZilla. Enter "dareftp.uol.de" into the "Server"-Field and click on "connect". Please confirm the use of the security cerfificate (necessary only once).

In the right part of the window ("server") you will now see the root directory of the server.

You can download an entire directory by following these steps: make sure that the directory in the left part of the window ("local") is the location you want to download the data to.

In the right part of the window ("server"):
