Why can't I open pictures DIRECTLY for a camera?

Copying the picture to the hard disk first is no big deal, in fact a smaller deal than removing the memory card and risking wearing out the camera socket.

I only offered that approach as an alternative to doing what you started off "complaining" about, namely copying the pictures folder to your hard disk using Windows Explorer (which is the only program you can use to do that since the camera only supports MTP-mode and no drive letter is assigned, and Windows Explorer is pretty much the only common program that can handle drag-and-drop from an MTP-connected device that does not have a drive letter).

And then I mentioned that once you discovered your camera doesn't support MSC-mode that you were going to have to compromise somewhere. I'd say accepting that you must use Windows Explorer to copy your pictures from camera to hard disk before you can use them in your normal image editing/viewing programs is in fact a compromise of sorts, especially since you now describe it as "no big deal" even though originally you were unhappy.

In fact it's just less of a pain and nuisance than removing the flash card from the camera and putting it into a reader... which means "it's the lesser of two evils", i.e. a compromise. But I agree, that it's really no big deal to have to do this.


Anyway, the bottom line is that the situation is understood, and information about the notion of MSC vs. MTP connection mode for USB has now been explained.

And it's now at least understood why you're forced to do what you've been doing, because your camera doesn't support MSC-mode. I point out that my Nikon camera supports both modes, but obviously not all cameras do.

Note that you are lucky that the USB connectivity of your camera is supported by Win7. My cousin's older Canon Rebel XT is NOT supported, and plugging the USB cable into the PC does not automatically make the camera usable!!! You cannot even do what you do, namely copy the pictures from camera to hard drive with Windows Explorer!!

For my cousin and this older Canon camera the ONLY solution is to remove the card, put it into the card reader present on her Lenovo K330 desktop and see the card as a Windows drive letter, and now she has full access to the card itself... as a drive letter. Newer Canon cameras are supported by Win7 [drivers] for USB connections, but the older Rebel XT is not.

So again... at least you can see the camera and get to it once you plug in the USB cable.

Quite so, but a USB socket is more robust than a digital camera's memory card socket. :)

Are you sure? The ones in cameras are very small, especially the ones with built in video.

Also, a new USB card is a lot cheaper than camera repairs.

But it's not the card that breaks.

I meant a PCI USB card you fit to the motherboard, which gets round any USB port that may have a fault.

Anyway, as dsperber points out, at least you have a camera that is seen by Windows 7. :)

Why couldn't Windows have been designed to create a fake drive letter to use PTP?

Yes, but I'd be more concerned about the tiny socket on the camera than the big socket on the computer (of which most have about 10 anyway).

It's just not part of the MTP spec, which describes a "device". It just works differently than MSC, which treats storage as a "drive letter".

Here's what my Cowon J3 "device" looks like when operating in MTP mode:



And if I expand the arrow (like "+") next to the "Cowon J3" device, it shows internal and external storage by name (i.e. the storage class names supported by the "Cowon J3" device), rather than with drive letters as would have been nice.



Same story with cameras connected in PTP/MTP mode.

Nothing we can do about it, I'm afraid.

Hands up who tried to click the arrow in the picture?

Surely the way it was designed doesn't prevent windows from treating it like a drive letter if it really wanted to? I wonder if there is a third party add on somewhere....

Actually it very much specifically WAS meant to not be treated as a drive letter. It was for situations where transcoding or format changes or DRM or special preview filters/custom programs etc etc etc were to be used when transferring files to and from the device which a simple drive letter does not allow.

The decision to allow one or the other or both is entirely up to how the manufacturer thinks that they want to best present the functionality to the user...

IMHO it's just simpler to take the card out. No need to drain the battery, generally faster and I usually have multiple cards in rotation anyway.

So what you're saying is Fuji are trying to force me to use their program to transfer it? Well Windows have got round that as I can copy them directly anyway. So why not just let me have a drive letter?

I agree completely.

But making the usefulness and user-friendliness of PTP/MTP even more miniscule, in my experience (and I played with this alot when I first got my J3) again only Windows Explorer seems fully competent to deal with the "device" and its "storage classes".

For example, when I was trying to use Winamp to create M3U playlists on the J3 while the device was connected in MTP mode (before I learned that the J3 doesn't support M3U playlists while it's in MTP mode... it only supports PLA playlists, while are ONLY supported, again, by Windows Explorer) I actually [naively] thought I'd succeeded!

Well, Winamp (like essentially 100% of all Windows programs) assumes the existence of drive letters to access storage. And apparently in attempting to SAVE the created M3U playlist file actually corrupted this Windows Explorer view of the device, because it really had no true understanding that "internal storage" wasn't a Windows drive letter. Fortunately this was just a temporary corruption (cured by disconnecting the J3 from the PC and then reconnecting), but it sure looked strange.

So it started like this:



Then I saved one M3U playlist on external storage of the J3 with Winamp, and it actually did go there. Of course the M3U playlist itself was unusable while the J3 was in MTP mode, and Explorer's presentation got corrupted as follows:



I was horrified and couldn't believe what just happened, so naturally I tried it again!! This time saving the M3U playlist file onto internal storage... just making matters worse.



Interestingly, once I learned that Winamp could not produce PLA playlists (which is what the J3 understands when in MTP mode), I also learned, again, that only Windows Explorer can deal with PLA playlists and MTP devices.

===>> MTP mode is not your friend, certainly not for portable music players where players/organizers/playlisters crave MSC mode because of the availability of Windows drive letters. It's baffling to me why camera makers would force MTP mode and not just choose MSC mode, if they're only going to support one mode.

I got my mp3 player for a couple of quid from china - beats the apple rip off ones! It is just a drive letter. Nice simple device - USB socket, headphone socket, 5 buttons (play/pause, louder, softer, next track, last track), and 2 LEDs (on/playing, transferring/charging). Charging done through USB socket. It is literally the size of a belt buckle, which is more or less where I clip it. 4GB storage, I didn't want to pay another quid for the 8GB!
