I am looking for an efficient way to move all of my messages (more than 50.000) in Inbox to another folder in Yahoo! Mail.

When I try in new version to Select All, only visible messages are selected, ie. if I then scroll down, new loaded messages are not selected, so I would have to scroll down for hours to load "manually" all messages.

Hitting End key to go rapidly to the last row is not working, and neither is Ctrl + End.

Trying on older versions is even slower.

Is there any other way?
