Be sure to follow these directions closely because manually manipulating the Zyzzyva data directory can be potentially dangerous to your data if you're not careful. You should probably read the full instructions before taking any action so you're familiar with what steps are required.
'''Note:''' In Zyzzyva versions before Release 2.1.0, the default data directory was a hidden folder named .Zyzzyva. You will have to enable the viewing of hidden folders to move that data directory.
# Open Zyzzyva and find out what your data directory is. It can be found by clicking Edit->Preferences and looking at the Data Directory setting in the General section. Copy and paste or write down this location.
# Open the Preferences window again, and click the Browse button next to the Data Directory setting. Use the file browser to find the new location of your data directory.
# Restart Zyzzyva, just to be sure it is using the new data directory. If it doesn't complain about missing databases, everything should be okay. If it does complain about databases, retrace the above steps to figure out where you went wrong.
