I am aware of the two conventional methods of removing an iPhone back up from the computer storage - 1) Through iTunes 2) by directly locating and deleting it using file explorer (on Windows)
Here's the problem:
Last night, I had at least 70GB of free space on my PC's storage. Then I backed up my iPhone, leaving my storage @ 10~GB free space after the back up. After backing up, I decided to remove the back up from the computer since it takes too much space, so I opted for option 1 - which is to remove the back up file through iTunes. However, this did not restore my 70GB disk space, it only left my computer with 18GB of free disk space. I've checked the back up file through file explorer but apparently it's gone already (probably deleted by iTunes). So now I am stuck with an unlocated back up file and 18 GB of free disk space. Hope someone could help me restore my 70GB. Thanks.
