| If you want a newer, fresher and quicker method to move a datafile from one disk to another here is the way to do it : Make sure the tablespaces are read-only and then 
 
 
 alter tablespace users offline;
 copy c:\mydb\users01.dbf e:\mydb\users01.dbf
 alter database rename file 'c:\mydb\users01.dbf' to 'e:\mydb\users01.dbf';
 alter tablespace users online; 
 
 then make your tablespaces read write again,
 and you're done :-)
