Move files with doubelspace in filename using CLIENT_HOST

Hi,

We have following code witten to move files in Forms 10g -

CLIENT_HOST('cmd /c move '||'"'||Source||'"'||' '||Dest);

The above code works fine for files with single space in filename. For Example - "a b.txt"

However fails for files having doublespace in filename. For example, "a  b.txt"

Any workaround for this.

Thanks.
