WOW ... a WHOLE lot of hassle !!!!! I have 20-30 wallets on my system ... should not be this tough.
Only 20 or 30!! That's nothing!!! Create a desktop shortcut to the roaming folder, makes adding .conf files a whole lot easier!!
I am sorry, I know its tough but thanks for the effort, you will not regret. We are working on a kind of electrum wallet, so soon this problems will disappear!
