Mac system itunes cleanup iOS backup files increase disk space method

When Mac users connect the ipad and the iphone to the computer, itunes automatically backs up some of the data on the phone, which takes up some of the Mac's disk space, so how do we remove the backup files in order to increase the MAC's disk space?

Workaround:

1. Open itunes and click "Preferences".

2. Switch to the "Device" module, select the backup you need to delete, click "Delete Backup" just OK.

This is the way to remove unused backup files from itunes, and if users don't want too much junk files to occupy their own disk space, then use this method to clean them up.
