Deleting a file will not prevent third party utilities from un-deleting it again. Secure file deletion utilities are available, however for casual use, you can turn any file into a zero-byte file to destroy the file allocation chain like this:
TYPE nul > C:\examples\MyFile.txt
Files are sometimes created with the very long filenames or reserved names: CON, AUX, COM1, COM2, COM3, COM4, LPT1, LPT2, LPT3, PRN, NUL
To delete these use the syntax: DEL \\.\C:\somedir\LPT1
Alternatively SUBST a drive letter to the folder containing the file.
If a file (or folder) still appears to be 'undeletable' this is often caused by the indexing service. Stopping the service will often enable the file to be deleted.

DELTREE - Older versions of Windows had the DELTREE command to delete all files and sub folders. This can be replicated with a script as shown on the DELTREE page.
Normally DEL will display a list of the files deleted, if Command Extensions are disabled; it will instead display a list of any files it cannot find.
DEL is an internal command. ERASE is a synonym for DEL
