For all the different things one wants to get rid of: files, folders, icons, apps...
delete deal with getting rid of unwanted content. This can be many different things:
- files and folders in the file-system:
- How to delete them
- Whether it is safe to delete xxx
- wiping the entire file system (delete everything in a safe, unrecoverable way e.g. from a stolen phone or one to be sold)
- Icons on the homescreen / notification area
- app data (including e.g. SMS and other messages)
