First, click the 'Upload' button.

 

Then drag in all the audio, artwork, video and other supporting content files you want to upload and then hit enter.

 

If selected correctly, Content Bank will now process multiple uploads at the same time.

 

Once the blue progress bar disappears from the Upload Icon at the top of the page, your uploads are complete.

 

These content files can now be linked to Assets (Audio + Video), Releases (Artwork) and other files (most areas of rightsHUB) to Attachment sections.
