I installed the wallet to a flash drive but I haven’t been able to successfully move all data out of the %appdata% location… when I tried to change all the paths in the batch file, the cardano-launcher.exe threw an error when launching.
I probably just fat-fingered something so I restored the batch file to the original and changed the DB path only and have been able to successfully run the wallet for the last week and made a few transactions to make sure it was syncing correctly.
I’ll probably step through each %APPDATA% var in the batch file and change one at a time to see if it’s supported. My main concern was to get the blockchain data out of the user profile directory which seems to be working fine by modifying the db-path switch in daedalus.bat to your desired location-
-n --db-path ^
-n “%DAEDALUS_DIR%\DB-1.0” ^
