I was trying to transfer iPhone pictures to disk. So I made a folder, selected the pictures I wanted (from the explorer window, because guess what, these devices are recognized and have drivers) and dragged the highlighted thumbnails to this new folder.
I tried again and again. Same result, nothing copied. I tried copying and pasting. Nothing happens. I installed iTunes, which did nothing. I tried connecting my Canon A520 to transfer a picture. Exact same behaviour. So...
I can view the files, I can load the folders, but I can't use them like normal folders for some reason. As a reality check, I grabbed a floppy disk and tried to transfer a file. That is normal.
Here's a weird detail. The Microsoft photo transfer wizard works. I can also save a picture opened with any software, but then it has to be resaved, typically recompressed, and so on. That's not a solution.
I could use my other computer and send the data over the network, but that's a workaround. So...I'm pretty pissed. No idea what happened. AV software running. Everything else totally normal. If I can't get it working, I have a backup from a month or two ago. Huge pain in the *** to save my stuff and load that, but it may come to that if I can't get my cameras to work
