Thunkable maximum file limit and not sure if that type of file is supported

I used disc image files which might be not supported and the size of the file exceeds 1gb, so I’m not sure if it supports that type of file and if it exceeds the maximum limit because when I added that file it’s not working nothing happens it just doesn’t add the file and also the file is .iso type but other files doesn’t work too

Thunkable Pro only allows projects to be stored only upto 1 GB so + those are not supported by Thunkable, if you add a disc image file which is ≥ 1GB Thunkable won’t allow it, you might wanna optimise your data, so it reaches ≤ 1GB
