Answer: When a computer system creates a file, it accesses the index file which maps it onto the disk or hard-drive. The index file keeps the information about where all the parts of the file are. When you delete a file, you delete the index file and so the computer cannot find the file. Parts of the file are still on the disk/hard-drive, but the computer is not able to find those parts.
