Renamed 'store' and 'retrieve' directories.

docker exec -it transfer_service bash

```

On this container, hosted on the so-called transfer node, each user will find his/her own home folder and two subfolders representing respectively the entry point and exit point for the user data:

- */home/name.surname/store*

- */home/name.surname/retrieve*

- */home/name.surname/vospace_store*

- */home/name.surname/vospace_retrieve*

The user will copy the data to be stored within the *store* folder, while he/she will find the requested data within the *retrieve* folder.

The user will copy the data to be stored within the *vospace_store* folder, while he/she will find the requested data within the *vospace_retrieve* folder.

This use case was implemented in order to try to offer support to users providing huge amounts of data in the order of terabytes.

Log files can be found in */var/log/vos_ts*.
