Yes, using FILE_SHARE_DELETE sounds like a good plan.  Be careful though:

if you delete the file, even though the DeleteFile succeeds, it still 
exists in the directory until the last HANDLE is closed.  So an attempt 
to create a file with the same name will still fail.  If you are 
deleting a file in order to create a new one with the same name, then 
you better call MoveFile() before DeleteFile().
