Prevent accidental deletion of files by creating a software for authentic deletion

WD My passport is an excellent portable hard drive yet there are some conditions where files can be lost without user permission.I am here to let you know that any folder(OF ANY SIZE) in the drive are prone to one TAP DELETION process.If we select a file and if we ACCIDENTALLY just tap DELETE button from keyboard the file is completely deleted without any pre notification.This procedure will happen for any file regardless of its SIZE.We all know there is a software available for overall password encryption for the external drive.But this doesn’t stop the one tap accidental deletion process and EVERY ONE cant afford for large size files to backup in Dropbox.
So i suggest to create a software which prevents accidental deletion like by providing to enter a password or key before deletion so that the deletion process is authenticated.
