Me personally even wonders why there is no simple "save to ...." option while installing/downloading a given wallet.
There is... Most of the "QT" wallets (ie the ones based on Bitcoin Core) ask where you want to put all the block data:
You should probably learn to slow down and read what the installers are actually asking rather than just clicking "next-next-next" as fast as possible
As for moving your current directory... you can follow this guide:
https://bitzuma.com/posts/moving-the-bitcoin-core-data-directory/As the guide indicates, instead of mucking around trying to use/set the commandline
-datadir argument, you can simply "trick" Bitcoin Core into moving it:
- Shutdown Bitcoin Core
- Rename (DO NOT DELETE) the current Data Directory
- Start Bitcoin Core normally and it will think it hasn't run before as it can't find the default data directory and it will ask where you want to save your data to...
- Specify the new (custom) data directory location that you want
- Shutdown Bitcoin Core
- Copy the contents of your OLD renamed data directory to the new data directory
- Start up Bitcoin Core and it'll continue on it's merry way using the new data directory
Alternatively, as you're on Windows... if you're comfortable making registry edits... you can change: Computer\HKEY_CURRENT_USER\Software\Bitcoin\Bitcoin-Qt
Look for the "strDatadir" value and simply set it to the new data directory location. Copy all the data over and then start up Bitcoin Core.
