This thread helped me solved a problem with moving the huge Bitcoin Core and Armory databases (150 GB total !!!) off my laptop and onto an external drive.
I am using Windows UNC paths to refer to both locations.
For Bitcoin Core, I modified the shortcut to become:
"C:\Program Files\Bitcoin\bitcoin-qt.exe" -datadir=\\myserver.mycompany.com\DriveE\Bitcoin
For Armory QT, I modified the shortcut to become:
"C:\Program Files (x86)\Armory\ArmoryQt.exe" --satoshi-datadir="\\myserver.mycompany.com\DriveE\Bitcoin" --datadir="\\myserver.mycompany.com\DriveE\Armory"
Note that the Armory shortcut needed to have double quotes for some reason.
This now works perfectly and I was able to delete the original Bitcoin and Armory folders.
Free space at last! Free space at last!
