Thank you for this. Saved me a bunch of time with external yammer communities that are not connected to M365 groups so no sharepoint site to download from.

Glad you could use my old code :)

@Saturate - thanks for this. Cleaning up old Yammer groups now that we have TEAMS.
NOTE for other users
I found that removing the popup.close section of the code was required when downloading over a slow connection, as the popup windows were being closed prior to the download being complete.
Code I used was

[].forEach.call(
document.querySelectorAll('.page-content .yj-tabular-data-name'),
function(el){
var fileid = el.href.match(//(\d+)$/)[1];
var downloadPath = "https://www.yammer.com/api/v1/uploaded_files/"+fileid+"/download";
var popup = window.open(downloadPath);
//I found the download tabs in Chrome closed when the download was complete
}
);

@dorjemrav happy that you could use some old code I forgot about :-) that's the awesome thing with open source. Have a nice summer!

I've a community with 700+ files; when I run this script, it times out after the first 50 or so. Can we easily add a short delay to the script so it opens a pop-up every 15 seconds?
