Deleting numbers spreadsheets on an ipad

You can delete a Numbers Spreadsheet in a number of ways.

From the file list of Numbers Spreadsheets, you can either touch-and-hold (i.e., a long touch) the filename to expose an Action Menu - and select Delete from the list of available actions.

Also from the Numbers file list, you can swipe to the left - exposing a delete option.

You can also delete Numbers (or any) files from within the Files App. Again, long-touch - or swipe - the gestures are the same.

Tap Sheet and in the dialogue box hit delete.
