Moving iTunes music to a new PC Issue

Apple's 6 pages of exhaustively meticulous step-by-step instructions: How to move your iTunes library to a new computer - https://support.apple.com/HT204318 Use this if you suspect any of your media are not in the standard location (iTunes Media folder).

My one-sentence summary if you always use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its sub-folders and files) intact to the other drive, hold down the option/alt key (shift on Windows) while starting iTunes, and when requested to select a library select the iTunes Library.itl file in the copied folder (Open a different iTunes Library file or create a new one - https://support.apple.com/HT201596).

See Make a split library portable. You've set the media folder one level too deep. It should be pointed to the iTunes Media folder, then each media kind gets its own subfolder, e.g. Music, Movies, TV Shows, etc. Changing the media folder to the default location and turning keep organized off and then back on again should work with this type of nested layout to get your media back into the usual places and make the library portable so that it can be moved by simply copying the whole iTunes folder.

I didn't say anything about moving files by hand. I recommended three specific preference changes. Undo what you did by putting things back exactly where they came from, and changing the media folder to its previous path. Close iTunes and reopen. Does it still show everything in the cloud? Did you move an iTunes Library.itl file? Everything going cloudy is usually a sign that your active library has been replaced by a new empty one. If the active library is supposed to be in <User's Music>\iTunes and cannot be found iTunes will create a new empty one without flagging up an error.

If needs be see Move your iTunes library to a new computer and revisit the way that you transferred the library.

Again, for the avoidance of doubt, in a well formed iTunes library the media folder is called iTunes Media and music files are placed in the layout ...\iTunes\iTunes Media\Music\Artist\Album\## Name.Ext.

Apart from the exceptions noted in Make a split library portable manually moving content or renaming files or folders on a Windows computer will break the connection between the iTunes library and its media.
