The help file above didn't help me much actually. how do I install all of the files to one directory. Its still installing the wallet on users/username/appdata/Dash ?? I want to have multiple wallets obviously with their own .dat files.
1) Close the Dash program
2) Rename wallet.dat to wallet_old.dat
3) Restart Dash-qt.exe
It will create a second (new), wallet.dat, which you can then rename to wallet_new.dat, or wallet_2.dat, or whatever you like...
Whichever one you want to load, rename to wallet.dat
Just be certain Dash wallet is not running when you rename wallet.dat files, and it might be a good idea to create a backup of both wallet.dat files as well
PS: Regarding backups,
https://en.bitcoin.it/wiki/Securing_your_wallet#Securing_the_Bitcoin-Qt_or_bitcoind_wallet...So when a backup is first created, it has all of your old keys plus 100 unused keys. After sending a transaction, it has 99 unused keys. After a total of 100 new-key actions, you will start using keys that are not in your backup. Since the backup does not have the private keys necessary for authorizing spends of these coins, restoring from the old backup will cause you to lose Bitcoins.
Don't rename files, it will get you in trouble. Just make a file called 1.bat which has this in it:
etc.
Then run 1.bat or 2.bat or...
