Question: large com.apple.bird directory
To be more specific: in "/Users/~user/Library/Caches" there's a "com.apple.bird" directory that's ~1.5gb. My Google-fu turns up virtually nothing on what this directory is, does, contains, etc. I'd like to delete it to recover disk space (not an readily available option to get an external drive or upgrade the internals).
Caches can be safe to delete because the app/process that uses it will rebuild it as necessary--sometimes. Is this a case where I can safely delete the "com.apple.bird" directory and move along?
I'm running Yosemite on a MacBook Pro (early 2011), 128gb storage.
Thanks in advance,
MacBook Pro, OS X Yosemite (10.10), early 2011
