Aspera - This is the primary uploader and downloader of files in CORE. Aspera provides high-speed data transfer solutions to send, share, stream, and sync large files and data sets.
Furthermore with Aspera, you can navigate away from the page without it affecting your upload. With the Simple upload option, navigating away will result in upload stalls/stops/cancels.
Using Aspera for uploads or downloads requires installing Aspera to your computer. You will be prompted to download Aspera if you don't already have it installed when choosing this option.
