To access the H-drive (homedrive) from home, you will need a SFTP program, e.g. WinSCP.
Type as Host name penti.arcada.fi and then type your Arcada username and password.
After you have logged in, you will see your H-drive files in the right field. In the left field you will see your own computer's files.
Mark the files you want to copy, and then drag them to the left field. Alternatively, drag the files to your desktop.
If you need to access files on the Arcada intra-server, move up in the folder structure until you reach root ( // ). Then choose intra.
