​I use the Remote Desktop stuff that comes with Linux (Mint).  That means that wherever I am in the world, I can log on to my home or office machine and do whatever I need, including fetching files, etc. 

Filezilla is another way of doing this, and perhaps even simpler.  But it is only for file transfer, not for a complete remote desktop session.  Dropbox or OwnCloud offer yet another very effective approach, and even offer mobile phone clients.  Not that I'd really want to read the Nyāyasūtravārttika on my mobile phone :-)

Being away from one's Mother Disk can be lonely, but the problem is soluble :-)

Best,
