Hi, thanks again. I am definitely not seeing File Management - my list stops at Create Folder. If I have time I'll post some photos later but am heading off on holiday tomorrow evening - hence my urgency trying to get these video files transferred!
I have registered my Archos and it says the firmware is up to date. The other problem I have is that I can't connect it to my laptop - the laptop doesn't recognise the Archos even though I have the latest Windows Media Player. So I can only assume there is a problem with it - I don't want to lose the videos I've recorded so can't reformat it (which is what my laptop keeps wanting to do!).
I have just downloaded a couple of file management apps from the App Library and will have a go tonight to see if I can transfer my files to the sd card using one of them.
As I suggested, if you have somehow corrupted your firmware, which is the only possible explanation (unless you're not really registered, but you say you are, right?)... reinstallation of the latest firmware should fix that.
Bear in mind that nobody's getting PAID to help you right now, nor is anyone here an Archos employee. Just "peers" telling you good advice. So, please go to the Archos website, confirm that you're still "in the system" as registered (if not, fix that), and then download the latest/greatest firmware, and reinstall it.
And please confirm that the "no file management" thing occurs ON THE FOLDER I SHOWED YOU, SPECIFICALLY. Remember, I mentioned that this is "context-specific." I can imagine that if you, for example, were to attempt to do certain things to, say, an SD card which was "copy protected," or perhaps damaged or corrupted, certain options would not be available.
Ultimately, I've given as much help as I can... and if your device really isn't working at this level, and if you've actually tried doing what was suggested (and it sure sounds like you disregarded my suggestion to reinstall the most recent firmware, frankly)... you're out of luck.
