I've got a 128 GB 11″ MacBook Air running Yosemite which I use for travelling and managing photos while on the move. With only 128 GB I try to manage the disk space carefully. But now I find there is only 10 GB left. About This Mac → Storage shows that photos take up 61 GB of this.
Drilling down 52.7 GB of this is in the folder ~/Library/Application\ Support/iLifeAssetManagement/assets/sub
which I understood to be Photo Stream. It shows in a very large number of folders, each containing a single jpg file.
But if I pull out the images by using the Finder window searching for "image" and then selecting from kind "image" (I understand the standard way to pull out Photo Stream) the resultant file is only 5 GB large
- Why is this folder showing nearly 53 GB when Photo Stream is only 5 GB?
- What constitutes the other 58 GB?
- How can I identify them and delete those I don't need to free up some much-needed disk space?
