I downloaded portable Electrum for windows from

https://electrum.org/#download

and extracted it.

It works, but it is not really full portable. All settings are not stored in current Electrum directory but in another user directory:

C:\Users\ts\AppData\Roaming\Electrum\

How can I tell Electrum (portable) to use a different directory for all its settings (e.g. the current directory or a sub directory "myset" for it?

Is there a cmdline switch similar to

D:\tools\bc\electrum\prgm\electrum-portable.exe -settings "..\myset\"

Mind the leading double dots as relative path to the brother directory.

Or at least

D:\tools\bc\electrum\prgm\electrum-portable.exe -settings "D:\tools\bc\electrum\myset\"
