MBA Storage question

[Labhras]

Hi all,
while using DaisyDisk for some cleaning-up, in my user folder the Library occupies 43GB so far, between Application Support, Containers and Caches. Other objects are present but with a size not sufficient to change anything. I wanted to ask you if you find this folder size to be "normal" considering I've been using the laptop for a couple of years, or are the files in these folders something I should/could delete to save space?

Thanks for the help

That sounds a little large, but hard to say without knowing what apps you have. Mine is about 6GB total.

In App Support and Caches you can delete any folders in there for apps you no longer have installed. If you want, you can delete the contents of Caches entirely, then reboot. It will rebuild caches for any apps you still have at a slight performance hit when that occurs the first time.

Backup first just to be safe.

In App Support I have a MobileSync folder of about 10GB which I suppose it's my iPhone backup with iTunes, a Java folder of 1.5GB and other smaller ones - Skype, Evernote, etc.
Then I have Containers where there are files like com.developer.app - like com.evernote.evernote, com.apple.mail, com.read.pocket...
Can I move the backup in another folder/disk?
And are the folders in Containers important for the apps?

Look here in iTunes preferences for any devices you no longer own and delete them. That will shrink down that MobileSync folder.

For everything else, if you still have the app, you don't want to mess with those folders.
