Hi Everyone!

I was hoping someone could tell me why this is happening!
I just got a card reader so that I can transfer digital pictures (jpg format) from my Mac to my Treo 650 faster. For some reason, after inserting the SD card and viewing the pictures through Resco viewer, I'm getting duplicate files.
For each file I transfer, there will be a non-working duplicate file with the same file name, but it will have ._ in front of the file name (for example ._IMG0123 in addition to the file IMG0123).
It never did this before when I transfered digital images using Palm's Hotsync software. Does anyone know what the heck's going on?

Thanks in advance for any advice!
