The steps for deleting a directory (folder) are the same as the steps for deleting a file. Please note that deleting a directory also erases everything inside of it.
First,
place a check next to the file(s) or folder(s) you wish to delete.
Then, click the "Delete" button at the bottom-right of the
table. A popup will appear asking "Are you sure you want to
delete these files?" Click "OK."
