Right, my mind is refreshed, here are the instructions for copying files from your pleo's memory using Dinomite.
I assume you already know how to use Dinomite enough to connect to your pleo and follow these instructions. If you don't, go to Dinomite's website and read up. If you don't know those things you definitely shouldn't be attempting file copying anyway. I also list only the specific steps needed for copying and nothing (or not much) else.
But first: the ever-important warning: ALWAYS make VERY sure that YOU DON'T COPY OR SAVE FILES ON YOUR PLEO'S INTERNAL MEMORY! If you accidentally create or copy files in your pleo's internal memory, there is no way you can delete them, and you can lock up your pleo and need repeated updates and reset its personality in the process of getting it back to life. DO NOT attempt to copy or create (by capturing images from the camera for example) files without being completely sure where they will end up and that you want them to end up right there.
I know, because I've done it myself :-) ... So if you feel uncertain in the least about anything here, go and read up (or ask in this forum, by all means). It's so much better to ask before your pleo loses it's mind than after. I have followed these steps myself just now, and several times before, but still, I can take no responsibility if you make a mistake or if I have written something incorrectly despite my care not to.
So, on with the actual steps required:
Insert your SD card in your pleo. Turn your pleo on.
Connect the USB cable between pleo and computer.
Open Dinomite, connect to your pleo.
Open the menu "View", choose "File system".
Make sure the current drive is B by clicking "Current Drive" and checking output in the terminal monitor window. Change drive using the button so labeled and its associated combobox if B isn't the current drive.
Click "File List". The files on the internal memory will be listed in the terminal window.
To copy a file, enter the filename, as shown in the file list, in the textbox which says <filename> by default. Then enter A:FILENAME in the textbox which says <dir>/<file> by default. This is the destination path, A: means the SD card, and it's critically important that you really copy to A: so you don't happen to create more files in the internal memory. Replace FILENAME with the name you want the file to have. It's of course easiest to keep track of things if you name it the same thing as it originally has.
Check the destination path again, make sure that it really starts with A:
Check the destination path again. If that feels silly, think about how stupid I felt when I ruined Gob's personality. It's worth feeling a little silly to avoid doing that to your pleo.
Click the button "File Copy" to perform the copy operation.
So, to copy plogfile.dat enter exactly that in the <filename>-box, enter A/plogfile.dat in the <dir>/<file> box and click "File Copy".
When done copying, close the connection in Dinomite and disconnect your pleo.
Turn your pleo off, remove the SD card and connect it to your computer to get at the files you copied.
There, that's the basics of it all. I would very much appreciate more eyes on this text. For comments and clarifications of course, but especially to make sure no mistakes have sneaked past me. You can never be too sure ...
