thank you my brother :)

Would you be able to update this to include video?

tastyhub, there is no RSS for videos at jw.org, and this means that such downloader would require parsing HTML pages and all the nasty tricks. All this won't fit into this simple RSS-downloading script.

I am working on a project to download material for offline use to use where there is no internet. I would like to find a script that I could setup to pull updates on all material on a monthly basis. I have tried to understand the logic of how the links work but they are some what random. There has to be a script of API somewhere. If you have any ideas please let me know. Thanks

Will this let you know if a new version of a file has been updated and inform you to download or auto download?
