How do I move wallet.dat file to a different location?
If you have already downloaded the data then you will have to move the data to the new folder. If you want to store them in D:\BitcoinData then click on "Properties" of Bitcoin.exe shortcut and add -datadir=d:\BitCoinData at the end as an example:


  "C:\Program Files (x86)\Bitcoin\bitcoin-qt.exe" -datadir=d:\BitCoinData
