It doesn't happen all the time, but every so often, after I load files (midi or audio) onto a USB stick from my Mac at home - inside the folder shows all these temp-type files of 0kb. They usually start with a "._" and then the file name like:
._At Last

Anyone ever see this? You can erase them one by one, but I haven't found a good system yet.

don't use a Mac .........

macs are dirty and leave trash everywhere they go!

I love all things Apple.

It NEVER crashes.
NEVER gets sick.
It's awesome. This is a small thing, and It's more than likely user error.

its not user error..they leave temporary files and 'trash' folders on every device you connect them too...its annoying. I am fortunate enough to own a Powerbook that I need for a couple of specialists programs, its nice computer, but I have always preferred ThinkPad T Series as my everyday machines due to the feel of the keyboard and better software support from a stable windows environment. But I do get the attraction to apple equipment and its nice to have a choice.

... I never even liked a 'Big Mac' ... prefer REAL burgers myself...

NO HIJACK !!!

You sure you are ejecting the stick from the Mac properly..? Remember, unlike a PC, you can't just pull the thing out willy-nilly. You have to unmount it first (and wait a few seconds until any LED flashing stops) before you pull it out of the Mac.

Next time you see those files, try to remember what you just did. That's always step one of troubleshooting. As it doesn't happen every time, something unusual is going on.

Most of the usual 'invisible' files (that less sophisticated PC based systems are not clever enough to not display) you see are .plist files and things like that. What you are describing is not part of the usual files on a stick or HD...

Invisible and System files are NOT visible on a PC (And haven't been for donkeys years) unless you specifically set it up that way.

Trouble comes from when one's file system is displayed on the other...

It's as easy to say that PC's are the same, because when their file systems get displayed on a Mac, THEIR housekeeping invisible files get displayed, too.

Neither is at fault, basically, as long as you stick to one system or the other. The problem comes when you take something out of one, and put it into hardware based around the file system of the other (as the OP has).

I'm guessing that the Korg is a PC architecture, so maybe they just don't show if you use a PC because windows chooses to hide them. It's a small point, and they ARE erasable ... just more time to waste. Maybe if I do my drag and drops while the 3x is hard connected via USB? Hmmmmmmm

Dave I believe it uses a Linux/Unix structure for the OS -but data storage is all FAT32 - they have not even extended it to FAT-EX, let alone NTFS. But as it is primarily for storage and not streaming it is pretty moot.

UD... Pretty easy to sort the file list in the Mac by filesize, and there are all the 0kb files in one lump, easy to grab and drag off to the trash...

Diki,
Can't seem to find the files when I look in the folders on the Mac - they are 4.0kb, but they do not show in the folders, and there is not a way to view hidden files that I know of. Anyone?
BTW - I found out that you can delete multiple titles on the kb, itself by holding the "shift" key and then tapping the title ... at least that saves some time. This is a puzzlement!

Tried this? http://download.cnet.com/Show-Hidden-Files/3000-2383_4-75415396.html

Diki,
I actually DID try that, and it showed some hidden files on my desktop pc, but not these little ghosts that seem to haunt the USB drives. Hmmmmm.
Any other ideas?

I'd just try a Google search about the specific problem, see what pops up...

Seems this is 100% Apple to non-Apple deal. Much like the way the iProducts are very proprietary, Mac likes to "deposit" these duplicate files every time it writes to a NON Mac disk. It's a tiny annoyance, and most of them can be erased, but it's visually cluttered. I read a few fixes that require software or Terminal commands ... I'll keep reading. Thanx all!

Its not a big problem as you say - just an annoyance as the mac leaves stuff in every folder (does it on any external drive). You can always ask a friend to plug a PC in at some point and get rid of all the mac trash. But make sure system restore is off on external drives otherwise the PC will leave a single invisible recycle folder in the root which is annoying if like me, you like your drives tidy.
