duplicate files on device

I am trying to find a way to find duplicate file with as much automatically(with out comparing individually)as posible. and \or being able to read all files in all dirs with out a call to each path. Thanks for any help

will the following "algorithm" do what you want :
1. Make a table with a column for filenames, define this column as "Unique". Other columns will include path for the file and other properties.
2. Search all directories and files, store all files in the table. If a filename is repeated the table will throw an error.
3. collect all errors using errorlabel and create a list of all the duplicate files (or another table, not unique).
4. With the stored path you can locate the duplicates.

Its a graet idea and will take care of the same name files. and will help with the others that are the same but different names. The other thing I need is to be able to compare by checksome/bytes. Thanks for your help
