The files of each MBS node or the timesorter are written to the ESR NAS by the RFIO server.
The server is running on the virtual machine atprfio.gsi.de. 
The NAS is mounted there and we write data to the subfolder: /mnt/raw.data/e0203_e0018/

This folder can be mounted to any x86l-XXX pc using litv-exp user with the shell command
> mountESR
The NAS is then mounted at /esr/usr/litv-exp/exp_mnt/data.ESR 
Which is where you will find the folder e0203_e0018 and the data.
