Where is config file for dosbox on uconsole?

When I play dosbox, which is installed by default on the uconsole, Which folder is the z drive shown on the dosbox actually in?
No matter how much I look it up in all folder, I don’t know where it’s set to z:folder.
I want to create a bat file because it’s so inconvenient to move to another folder using the “mount” every time.
Or is there a way to specify it as a folder other than the default folder when I start dosbox?

1, Where is the actual location of the z drive in dosbox?

  1. Is it possible to designate it as a different folder in the first place when running dosbox?

  2. Where is the dosbox config file. ?

I found dosbox.conf in /home/user/dosbox,
and I edited config
