Dear Bhante K,
With your leave.
Please follow the steps below(windows system):
Once you are in, click on the "Shared" folder
Next, click on the "06-Pali Studies" folder
Now you can either click the available folders to open them or you can download the whole folder (see highlights)
This is the view when you open the folders. You can individually download the lessons as you wish.
Hope this helps you out
with añjali and mettā,
