I have a lot of files on an external drive to my new MBP and there's too many of them for the internal 500GB SSD (and no second drive bay to make a fusion drive or have a second drive in latest MBP which is completely crap BTW Apple).
So I need to have my usual Finder shortcuts to directories deep within the data tree. Problem is if my ext drive is ever switched off or disconnected why my MBP is on the shortcuts get removed by Finder and don't come back when drive is reconnected. My usual method of making these shortcuts is just to drag a directory from the Finder file list into the Finder window sidebar. I'm not sure what this actually prompts behind the curtain of OS X as it's opaque (to me at least) as to whether aliases are stored somewhere or symlinks or so other class of object to track the location.
I'm wondering if I can create shortcuts to symlink files on my internal SSD that link to directories on my ext HDD as a work around to this very frustrating obstacle.
