**Note: You may only remove files if you are the owner of the Channel, or if you've added the file to the Channel.
If you wish to take files out of a folder, first navigate to the folder under the Files tab in the channel.
From here you have two options:
1. Take the file out of the folder by dragging it up to the path that says Home
2. Completely remove the file by clicking the down arrow on the right hand side and then Delete
If you delete the file it will no longer be accessible to your Channel contacts, but it will still exist in Your Files.
