I dumped a bunch of files (music and otherwise) onto my shiny new Macbook, and since I'm more comfortable with linux than Mac (at this point) I tend to use the terminal.

I did a ls -al on the files I'd transfered, and some had an "@" at the end of the permissions string, and some did not.

Something like:

drwxrwxr--@ 93 user staff etc.
drwxrwxr-- 107 user staff etc.

The ones without "@" could be seen in Finder and accessed by other programs-- the "@" files and directories were invisible. Can anyone explain what the "@" means, and how to chmod (or whatever) so I can use these files? I assume it is some sort of system flag but I don't know how to unset it. Chmod 777 had no effect and I already own the files.

Thanks
