-## Via Command Line Interface
-
-You can directly transfer your data via the terminal using the following commands.
-
-**Important**: you need to have your VPN connected to HT.
-
-```bash
-scp /localmachine/path/file <username>@<ip_vdi>:/path/where/to/upload/
-
-#if you want to transfer a whole folder, add -r after scp, as follows
-scp -r /localmachine/path/folder_name <username>@<ip_vdi>:/path/where/to/upload/
-
-#example
-scp -r /mnt/D/Data/luc_raw_folder [email protected]:/home/DL4MIA/data/
-```
-
-**Important**: `scp` overwrites the data if you already copied it there.
-
-If you don’t want to overwrite data and only if there are changes, use the following command, very similar to previous
-
-```bash
-rsync -avP /localmachine/path/file <username>@<ip_vdi>:/path/where/to/upload/
-
-# to transfer a folder, do the same, but without the last '/'
-rsync -avP /localmachine/path/folder <username>@<ip_vdi>:/path/where/to/upload/
-
-#example
-rsync -avP /mnt/D/Data/luc_raw_folder [email protected]:/home/DL4MIA/data/
-```
-
-To download data from the VDI to your computer, change the local and vdi arguments so that the vdi comes first, as:
-
-```bash
-scp -r <username>@<ip_vdi>:/data/path/in/vdi/ /localmachine/path/to/download/
-```
-
-## FTP client
-
-One could use an FTP client such as Filezilla (all OS) , WinSCP (Windows), Cyberduck (MacOS), etc. These allow you connect directly to the machine and upload or download data:

-> **Important**: you need an active VPN connection

-```bash
-host: <vdi_ip>
