[ale] 117000 files vs 240 missing - amazon

A vendor put a site on Amazon with some files we need.   We don’t have sftp access to this Amazon site but do have ftp access.

Accordingly we did a wget to download all the files using our ftp credentials.    When all done we got over 117,000 files and saw no errors in the wget.

The problem is vendor is telling our director there are 240 more files in their count than we downloaded.    This is less than a 0.2% difference so I suspect it has something to do with the way they count vs. the way we did.  (We used find piped to wc –l.)   Our count matches the summary wget output when it finished so we are sure we’re correctly counting what wget did but of course it’s possible wget actually missed something though it seems unlikely to me.

The question is does anyone know what might cause such a difference?  Alternative does anyone know another way we could count the files on the Amazon site using our ftp credentials other than going in and counting them one by one?

We’re trying to find out how the vendor did their count but I was hoping someone already knows of some vagary on Amazon sites that would cause this kind of discrepancy.
