Not a problem to keep coming back. It is difficult to accomplish these tasks over forum posts without in-person interaction.
I have to guess what happened based on your responses. The better the details you provide, the better guesses I can make.
You said:
I have left Organise Libraries checked.
but I think you missed the second option unchecked. You need to have
Copy New Items into iTunes Library is checked in Edit->Preferences, Advanced in iTunes.
Setting this option copies the files off of the iPod to your computer.
Forgetting this option will create a library with tracks that are on the iPod. When the iPod is ejected, the songs will show in iTunes, but can't be played.
Steps 7 can be tricky. Based on you saying
I don't understand why the "songs" all F1-50 files are in the file manager but the iTunes Library in the app remains empty.
I am guessing this didn't get completed like it needs to be. I built a composite of both pictures to attach. See the dark side of the picture, on the right side of that is the search box. This where you put the
*.m4a OR *.mp3 OR *.m4p then press the Return button to search.
The F1-F50 are the folders in that directory, they cannot be imported into iTunes directly the search from Step 7 needs to happen to show the files.
If the search is used, then there will be a list of files each with a 4 letter name and 3 letter extension.
DHGR.mp4 and
KZZO.mp3 for example.
The list of files needs to be selected, not the folders.
Step 9 is hard for some people. (Drag the tracks from File Explorer and drop them onto the
Library section of iTunes.) What I do is put iTunes on the left half of my screen, and the File manager on the right. The "Library" section of iTunes is in the left column at the top. I have attached a picture where to drop the files in iTunes, it is the light colored part of the picture.
You can tell that the import is working by looking at the middle bar at the top of iTunes, it will show a count of files being imported. If it just shows the Apple symbol, then no import is happening.
If your computer continues to not work with this method, I can add a couple steps to do it in stages. Even on my older computers the stages way worked every time.
Let me know how it goes.
