I surf in the internet with Safari. When I download a file, it is automatically saved into the default directory "Downloads".
I usually download pdfs from http://arxiv.org and https://journals.aps.org and I would like to automatically save those pdfs in a different directory, say "Papers", without using "Save as" and then choosing the directory.
In other words, I want to modify the default download directory only for specific URLs such that only files downloaded from these URLs are saved into the second directory. All the rest of the files will be stored into "Download"
Is there a way to do so? Even a button in the Safari Toolbar is ok
