Same problem. > > Then I did a cp -R of the directory itself from my hard drive to the > flash drive, and voila! All files copied, no problems, except that > now the files are in a new directory of the same name on the flash > drive. > > The total number of files in the base directory is 171, and the total > size of the files copied was a little over 500MB, so I believe that > everything should have fit just fine.

If you had long names they can take up to 20 entries for each file. http://en.wikipedia.org/wiki/Long_filename -- MailScanner is like deodorant...
