Yes, of course you can. You need to go to the monitor and change the location. I use a 32GB (!) USB drive and I hace re-dircted the content to the E: drive. Do you know how to do it?
1) Keyboard/Mouse onto monitor - press Alt-F12 to get out of magicinfopro client
2) Rght click on the globe (bottom right hand corner of Windows bar - next to time
3) Select EWF and Disable it - reboot
4) Do as above again
5) Right click on the globe and select Setup --> Screen and select the option from D: to E: drive
6) Apply and close
7) Enable EWF
That's it...!
I hope it helps. Bill
