Speaking of bluetooth transfer ...I just finished transferring about 800 mb of graphic work from my n800 to my comp....took a few hours...yeah...wifi is quicker...usb quicker still...transfer speed is dependent on many factors....I know that 1 file at 800mb will transfer much faster than 2317 files at 800mb ...for example.

Geez...been doing so long...don't even really think about a step by step.
Hmmmm....Simply put... the point is to enable your nxx0 device to access a specific file folder on your pc.
As far as your pc goes under devices enable wifi or bluetooth or both....make sure your pc is visible for it... for that nxx0....and the same for the nxx0 to see the pc.
once you are able to have both devices see each other ...drag and drop files onto pc folder designated for transfer...(the key point is the specific folder you wish to enable sharing must be enabled to share...ie permission to share).... Then access shared devices on target nxx0 ...and simply move files to a locale in your nxx0 file system.

I know this seems a bit vague in explanation...but explicit directions do vary depending on the specific p.c. o.s. .
