itunes 12.6 does not allow drag & drop to create a play list. What to do instead?

I did that, but it didn't work. Is there any other free software which can be a good substitute for itunes? My problem is that I have 900 GB of nearly 2000 audio books which is a lot of audio files. I want to be able to create a playlist with the name of each book because let's say each book, for example, has 20 tracks, track 01, track 02 and so on that makes it impossible to sync them all in itunes library and then create playlist. So the only option is to drag the folder and drop, but **** does not work.

I've done everything before creating this topic. I even uninstalled itunes, bonjour, apple software update and... then deleted everything with the name of apple from my whole system, hidden or not hidden. Then reinstalled itunes again, but the problem still exists. Here is what I do: create a playlist>edit playlist>clearly see on the right where it says drag and drop itmes to add to the playlist>I drag a song or folder>I bring it there but the cursor shows a prohibited/stop sign>I release the click to drop it and nothing happens. Others have also had this issue, I've tried everything they said on the net, but it does not work. Oh and I'm not gonna call apple support coz you know better than me that it is a waste of time. I've tried other software such as ifunbox, but coz of apples tight and close ecosystem, nothing worked.

I already did that, but it didn't work. Now some body told me to download this and use it instead of itunes:

Apowersoft Phone Manager PRO 2.8.8 مدیریت دستگاه اندرویدی و iOS در ویندوز - دانلود رایگان .

I will install it and see if I can get through. If so, then definitely itunes will be a lonely software in my PC. I think if apple wants to fight with Microsoft, they'd better kick out office from app store, not depriving the PC user from the very rights of drag and drop, just to make them move towards apple. Of course, I was thinking about migrating to iMac, but this is really insane. My PC still works, so I don't wanna waste some money on a new machine.

Ok I did install Apowersoft Phone Manager, but that has its own issues. To create a playlist, it does not select folders, but the MP3s in the folder itself. Now let's says I wanna create 1 playlist for my favorite singer who has 20 albums (folders), then this is impossible and I have to create 20 playlists for that specific singer.

I'm on Windows 10 and I do exactly what you did, but as soon as the mouse cursor (that has the shortcut of the selected files hung on it) enters the border of itunes, it becomes like a stop sign and after I release the click, nothing happens. Songs are not added. I think you are in windows 7 and that's why you can do that. Maybe it's something wrong with Microsoft.

I know what you're talking about, but I've done that before. I've disconnected iphone, created a playlist in main itunes menu, draged files and same thing happened. I really don't know what the **** is going on with the drag and drop. All I can say is stay in windows 7 and never ever update your itunes coz you'll be stuck in the same situation. Do you know if there is anything I can do with, let's say ifiles or anything else? Of course that is another pain in the chest coz I'm on iOS 10.3.3 which is not jailbroken yet.
