can i delete "developer-old" folder?

I've got a "developer-old" folder besides for my "developer" folder. "developer-old" contains "headers", "SDKs", etc folders.

It'd be nice to delete this folder bc it takes up 10GB. Can I?


Solution 1:

Yes, you don't have to keep that folder according to https://discussions.apple.com/thread/2780986?start=0&tstart=0

/EDIT

It's the backup of old Xcode installation.
