Thanks. As I already have a wallet on the pc with DASH in it...when I install and start the new wallet it always load up the previous .dat file. Is there a way to load the load all from one folder? I still don't understand where the wallet.dat files are being stored for the individual walltets?
The wallet.dat file is your wallet... it hold all your keys, and signs your transactions... This is an important file you should save a copy of and keep in a safe place
If you rename the wallet.dat file to anything, the next time you load the wallet program, it will create a new wallet.dat file, which is different from the one you just renamed
See noahs reply above for a way to swap between multiple wallets without renaming them back and forth.
