How to delete some of the uploaded media in cloud storage?

How to delete some of the uploaded media in cloud storage? I can't find any webpage can do that in the new version.

If you delete the file from Presenter's Media library, that should remove it from the cloud. If you don't want to completely delete it from Presenter, you can click on the "i" icon that shows up when you hover over a media file. On the following pop-up window, click "Remove" next to "Saved in Cloud."

If you feel that your cloud storage is not calculating properly even after you've deleted things from your Media library, email [email protected]

Feature Request:
Please provide a file storage option for data managment similar to the one you have for uploaded files in the charts app. I need mass edit rather than going through each individual media file that needs deleted. Spent 30 minutes doing something that should have taken like 3.

Bulk deleting is supporting in Presenter - switch the Media Library viewing format from Thumbnail view to List view.
You'll find the icon for this to the right of the "Import" button on the Media page
