Short answer: no, don't worry about it.
Longer answer:
Extended file attributes are metadata associated with the file. They can contain virtually anything - author name, URL where the file was downloaded from, a hash or checksum of the file. Some programs might use that metadata (I think Dropbox uses them). There is a
Wikipedia article on extended file attributes.
Flash drives usually use a file system called FAT32, which doesn't support them, hence the message.
