Where is the iPhone backup file located on my Mac computer? I created the backup with iTunes for Mac.

If you used iTunes for Mac to create a backup of your iPhone, the backup file will be located in the "/Users/{userid}/Library/Application Support/MobileSync/Backup" folder.

A sub-folder will be created for each backup. For example, here is an iPhone backup sub-folder:

fyicenter$ cd ~/Library/Application Support/MobileSync/Backup
	
fyicenter$ ls -l 45219035443f09dccbcc469473f487ca5aee9f5a
total 117760
