My Link capacity is the total amount of available links with an expiration date you created.
For links with expiration dates, Free members can create My Link up to 10GB, and Send Anywhere Email Add-on subscribers can create more My Link. Lite members can create My Link up to 300GB, and Standard members up to 750GB.
Once My Link expires, it automatically frees up My Link capacity. You can also free up My Link capacity if you delete the unused My Link to create a new one.
