Your mistake was in changing the contents of your music folders using Windows rather than through Itunes. When you make changes like this there's no way for Itunes to know you've added or removed files. But if you do all your file maintenance through Itunes everything is done for you in Windows as well.
Your best bet, assuming you are absolutely sure your new, selfmade music folder is complete, is to trash the current Itunes library info and then add everything back. This is quick and easy. Again, make sure that ALL your music is in this folder you've made on the external drive. Have a look around your local music folder just to make sure.
1: Trash the current Itunes library
Run Itunes.
Select all your music.
Press the delete key.
You will be asked if you want to delete the files from your library or from the computer. Choose the option that ONLY deletes them from Itunes but leaves them in their place.
If you have podcasts, movies, TV shows, audiobooks, etc delete them in the same manner. Remember, they're all in the music folder you created so we're just making Itunes forget about them. Keep doing this until you have no media at all inside Itunes.
Now open the preferences. Under 'Advanced' look for the Itunes library location. It's probably local, on your C: drive. Change it to F:fixed_music or something similar. Just make sure that F: is the name of your external drive and 'fixed_music' is NOT the name of the music folder currently containing all your media. It shouldn't even exist yet.
On the same page check 'keep itunes music folder organized' and 'copy files to Itunes music folder when adding to library.' Then hit ok. Restart Itunes.
So now you have an empty Itunes, and brand new 'fixed_music' folder, also empty, and another folder full of your music. Drag that folder onto your Itunes window. Everything inside it will be both added to your library and copied into the fixed_music folder. It will take a while.
You probably realize you now have duplicate music folders, right? Check the properties of your original folder and compare it to the properties of the fixed_music folder. Same number of files and folders? Perfect! Have a look around Itunes to make double sure everything's there. Now throw away your duplicate music folder (the one you made yourself). Or keep it for a few days to be on the safe side if you like. But fixed_music is your new, permanent music folder.
From now on just drop any new music onto an open Itunes window and it will be copied to the music folder and added to Itunes. So if you have a folder with 10 new mp3s on your desktop you just drag that folder onto Itunes, wait for the copy to take place, and then throw away the folder on the desktop.
If you run itunes without having the external drive plugged in your music folder will reset to the c: drive and new music will be added there. Syncs will still work, but remember every once in a while to plug in your external, change the location of the itunes music folder in the preferences, and then choose file>library>consolidate. This will copy all the local music over to the proper library, after which you can delete the contents of the local music folder.
Good luck!

Mixxx is free and open-source software for DJing. It is cross-platform and supports most common music file formats. Mixxx can be controlled with MIDI and HID controllers and timecode vinyl records in addition to computer keyboards and mice. Mixxx can read most popular audio formats, including MP3, Vorbis, Opus, AIFF and FLAC. When you’re done with the sync options, click Done to re-sync again with the new settings.
