Hi All,

I am trying to download the core density files from the website [core\_electron | ABINIT](https://www.abinit.org/core_electron), but failed. Clicking on a blue-highlighted element in the periodic table didn’t start the download. Could anyone help me out?

Thanks,  
A

We have changed the protocol used for downloading : ftp:// to https://  
It seems that some browsers do not support natively the FTP protocol : after 50 years of good and loyal services, FTP can retire! 😉
