Thanks mediavets, you constantly save me.
No problem - your question is quite reasonable, I had the same issue myself back in the day.
I cannot see the Nokia on the LAN
No, nor can I - but I can see the LAN from
the Nokia File Manager - see screenshot - and can drag-n-drop a file from N810 to shareddocs on a networked Windows PC over WiFi, it's a slow process, appears not to be working for a while, but it works for me.
But I usually just connect my N810 to the PC using a USB cable and transfer files using Windows Explorer from the N810 which appears as two new drive letters - one for internal memory card and the other for the external memory card.
but I will try to connect a stick via the usb (I don't have the cable at the moment).
Perhaps you misunderstood me before? - I connect the N810 via USB to the PC; I do not conect a memory stick via USB to the N810. In theory if you have a special OTG USB cable that may work - but it hasn't for me. You can also get a small software utility (fro the N810) to switch the USB mode of the N810 USB port but again it's not worked for me. There is very limited power available on the N810 USB port; it might work via a powered USB hub; but hey, it is far easier to hook up the N810 to the PC via the standard USB cable that comes with it. There's nothing special about that cable, any USB cable with the correct conectors will work, I am currently using one from a Nexus 7 Android tablet.
If you need to get a file quickly from N810 to the PC, and lack a cable, you could use any on-line file sharing service too.
