I suggest you stick with files default locations if not comfortable with changing it - or set rclone config location env variable - check on rclone website its exact name. It is something like RCLONE_CONFIG_FILE
What I would like to add:
I had a working restic setup on windows with a repository to onedrive over rclone. All necessary files (restic.exe, rclone.exe, password-file, my scripts) are located at c:\tools.
So I placed Restic-Browser.exe also there and created a batch file to start it. At the beginning I could not make it work, Restic-Browser would always complain about something like "c:" does not exist. I got it workind then with slashes instead of backslashes
SET PATH=%PATH%;c:\Tools
Restic-Browser.exe -r "rclone:onedrive:/restic-backup" --password-file "C:/Tools/pwd.txt" --rclone "C:/Tools/rclone.exe"
