If you have one of the famous Apple devices then you might need to know where the iTunes media folder is. This is the folder where your music, videos, and other files are stored on your computer. It really doesn’t matter if you are using a Windows computer or a MAC because the iTunes media folder simply holds the media for all systems.
The most common reason for accessing the iTunes media folder is to backup your iTunes media files.
Where is the iTunes media folder in Windows?
1. Open iTunes and go to the edit menu at the top. For a Mac go to the iTunes menu.
2. Choose preferences from the menu. See the screenshot below.
3. Click on the Advanced icon.
Now you know where your iTunes media folder is so you can backup the files or transfer to another computer.
Here is a note about the iTunes media folder from the Apple website:
When you purchase or import media into iTunes from a CD, it is automatically added to your iTunes Media folder. However, if you add media to iTunes another way, such as by choosing “Add to library” from the File menu, or by dragging a MP3 file into iTunes, it may or may not be added to your iTunes Media folder. This is determined by the preference to “Copy files to iTunes Media folder when adding to library.” Enable this option to be sure all your media files are stored in the iTunes Media folder; this makes transferring or backing up your media much easier since it is all in one location.

This is why it is recommended that you tick the box next to Copy files to iTunes media folder when adding to library. This will ensure that all new files are automatically added to the iTunes media folder.
