I do it one of two ways
:
with SD card reader:
put SD card in reader slot,
then it pops up a meesage in Windows asking how I want to view the files,
I select "...using Windows Explorer",
then the folder pops open,
I right-click, select "Copy",
and then right-click, "Paste" in a folder I've created on my hard drive,
then re-insert SD card in camera,
turn camera on, and re-format.
with USB Cable in K100D
I connect the USB cable to the port in the K100D,
then I turn on the camera,
the same prompt pops-up,
I select "...using Windows Explorer",
folder opens,
right-click, "Copy",
open new folder on my hard drive,
right-click, "Paste",
turn off camera,
remove USB Cable,
turn on camera,
reformat.
I Hope that this helps.
