To destuct sensibel data.

If you delete one file, you can restore it with 'undelete'. 

Whiping a file desrtuct it total by writing 01010101 and then 
10101010 in each byte of an alocated sector/cluster.

You must read the FAT, where the file begins and then whipe each 
Byte at the end of the sector/cluster is a pointer to the next 
sector/cluster and you continue until EOF or better EOC.
