Wiping free space means it removes traces of data on the hard disk of the previously deleted files i.e the wiped space can no longer be recovered by recovery softwares its perfectly clean.

Wiping Free Space is not that much necessary unless and until you are giving your hard disk to someone or you are going to trash your hard drive... what happens is that when you delete a file windows only deletes the registry entry that points to that particular file... it doesn't completely remove it from hard drive... now when you place any file on that memory location the previous orphan data gets overwritten... to securely delete data wiping is needed as there are many tools available that can read the existing data of hard drive (that is not properly wiped) and thereby give away important information like credit card numbers... again there is depth of wiping... more the security implied, more the time it will consume for wiping purpose.
