“Hi guys, A quick scan with the incredibly useful “Disk Inventory X” shows me that my iTunes library is getting a bit big for my new, 300GB computer hard drive. I had a 500GB before on my old device. Is there a simple, one step process that can downgrade the file size from the larger ones.”

A good point and concern. We will share 3 methods to reduce your iTunes library size to free up space and speed up your iTunes in this article.

Remove duplicate media files in iTunes

To delete duplicates in iTunes, run iTunes and click Music, Movies, TV Shows, Apps, etc. under Library, then choose View> Display Duplicate Items.

Shrink the music size

Reducing the music file size in iTunes is also a good way to save space.

Generally,  192 kbps is perfectly enough for your  music quality. We recommend you to pick those music at 256 or even 320 kbps bit rate and reduce the size of those selected music file.
