By default Windows 10’s WSL has trouble opening paths VeraCrypt volumes. This works around this limitation.
open-wsl-here.reg adds a registry key to add the “Open WSL here” context menu item (based on https://www.tenforums.com/tutorials/60125-open-bash-window-here-context-menu-add-windows-10-a.html). This creates a file called “wsl_path.txt” in your temp directory.
Next you need to add source wslpath-veracrypt.zsh to your .zshrc and it will automatically try to read the “wsl_path.txt” file and switch to the directory indicated by it if the file was modified not longer than one minute before.
Since environment variables are different between Windows and WSL, you might need to adjust the paths if your Windows username doesn’t match your WSL username.
When you start your first WSL shell, all the currently active drives are mounted. If new drives are added later, you need to manually mount them using
sudo mkdir /mnt/a
sudo mount -t drvfs A: /mnt/a
