To delete an item from the Media Finder, simply right click on the item and click Remove or click the Trash Can icon on the top of the media finder.
The item will be placed into the Recycle Bin and removed automatically after 14 days.
If you wish to delete multiple items from PlayoutONE, you can either hold the Control key on the keyboard and individually select the items you wish to remove. Or alternatively, you can select a range of items by left-clicking on the first item, and then shift-clicking on the last item in your range. You can then right-click and choose Remove as normal.
To bypass the Recycle bin, hold Control and click the Trash Can icon on the top of the Media Finder.
