Not long ago, I could transfer pictures and videos from my computer to my iPod Touch using Explorer. Now I cannot. Neither Windows XP or Windows 7 Explorer will recognize the iPod. iTunes seems to work ok
Although this is primarily an iPod/iTunes discussion, many computer folks may find this informative. This is what I have learned about the iPod:
It is not a device like a camera where it is recognized as a device by the computer and where you can have access to the memory via Explorer. For those who do not have a computer background and do not think of it in this way, it may be simpler to understand and use.
There are five what I would call levels of memory. Three are controlled and accessed by iTunes and not the computer. One is not accessible or controlled by either. And one is only accessible for output only by the computer. In only one instance is a memory recognized as a device and is visible by the computer.
Level 1--Downloaded music and videos: These are downloaded via iTunes and are accessible and controlled only by the device and iTunes. Perhaps this is to prevent piracy.
Level 2--Music and videos inputted by the user: These are installed and synced via iTunes from the computer. For ease of use it is best that these be placed in a special folder which is easily identified by iTunes. By manipulating and re-syncing the folder, files can be put into or removed from the iPod. The iPod device cannot delete these files.
Level 3--Photos and videos inputted by the user: This is similar to Level 2 except treated as photos instead of music in iTunes. Again, a special folder in the computer is helpful.
Level 4--Selfies: These are not controllable or visible by iTunes or the computer. The only way these can be removed is via email. A terrible arrangement! All but the last one can be deleted by the iPod. One seems to stay in the iPod forever!
Level 5--pictures and videos taken by the user: These are the only ones accessible via the computer-recognized-device and Explorer. Furthermore, if there are no pictures or videos available in the iPod, the computer will not even recognize the iPod as a device. This arrangement is why you do not see the iPod as a device under normal circumstances.
Finally, iTunes does not like to be open and closed repetitively. Also, sometimes it will hang up. After each session, it is best to unplug the iPod, reboot the computer and then plug the iPod back in. In this way the re-syncing process will take place normally and the iPod will be detected.
