When you're logged in to your Plus account, you can open the Transfer overview by clicking on the 'transfers' tab.
In here, you can see all the uploads you’ve done while you were logged in to your Plus account. It shows you the number of transfers and the amount of storage used.
The list of transfers is by default sorted by date, with the most recent upload at the top. You can sort the transfers by name, date or recipients.
