eliminating large numbers of duplicate files.

[Tom Harrington]

When working with a new program, it somehow managed to
multiply a geat many files times 6!

Is there means in Windows XP to eleiminate the duplicates
automatically while leaving the originals in tact?

If not, is there an aftermarket program which will do the
job automatically?

Thanks very much for taking the trouble to answer me. I do
appreciate it.
