LUA: import image from USB

I've also been looking into this

This bit of code lists drives, excluding OldVersions, similar to the Cmd "List Drive"

local function main()
    local drives = Root().Temp.DriveCollect
    for k, v in ipairs(drives) do
        if v.drivetype ~= "OldVersion" then
            Printf("Drive #    : " .. v.no)
            Printf("Drive Name : " .. v.name)
            Printf("Drive Path : " .. v.path)
            Printf("Drive Type : " .. v.drivetype)
            Printf("")
        end
    end
end

return main

What I'm struggling with is how to get the Import & Export Lua functions to reference the USB directories instead of the internal file structure.

Just select the appropriate drive as part of your script.

Try using the Drive keyword first before using the option keyword /Path:

Also, you should learn about the library keyword for files you want to import:

Library Keyword - grandMA3 User Manual - Help pages of MA Lighting International GmbH

Import Image Library "myImage.png.xml" At Images "Images".1 If Drive 2

This would import the file from the first connected USB drive.

Also make sure, that an XML file exists correspondingly to the image file.

You can force the creation of XML files for media files by using the UpdateContent keyword:
