How can I search for path/filenames that are over 255 characterslong which is not allowed in Windows Vista

Say I extract files from a compressed file and I do this a couple of folders
deep - say in: C:\Users\Todd\Pictures\Professional Logos And
Pictures\Company Logos\Larger Than 100x100\

And when I extract a file in this folder it has files that are several
folders deep - creating a path and file name that is greater than 255 (or
260) which Vista allows to be created but if I say goto copy and paste the
folder \Larger Than 100x100 when it comes to a file that is greater than 255
there is an error and says can't copy the file XXX.xxx because th filenam is
to long.

???? How can I search for all the files that are over Windows Vista naming
limit of 255 or 260 characters (not sure how many it actually is - it is
either 255 or 260)?

Any help appreciated.

TIA
