The 750-Gb hard drive on my MacBook Pro has filled up, again.  While searching for folders and files that I may eliminate from it, I ran across the folder ~/Library/Application Support/Macintosh HD/.  It occupies 200 Gb: more than 1/4 of the whole HD.  It seems to contain a copy of my HD as it was some time last year.  It even contains old versions of my user data files that, in their normal location, I have since updated many times.


How did this folder get created?  Is it safe for me to move it to the Trash and then empty the Trash?

MacBook Pro, Mac OS X (10.7.5), 17" late 2011, 2.5 GHz i7, 8 GB RAM

    If it is truly a duplicate and all the originals of the files are elsewhere, then you should be able to; however, messing around in the Library folder is not to be taken lightly. So, you could move the folder to the trash, but do not emptyyet.  Or,  copy it to an external for safekeeping and then move it to trash and empty. Now restart your computer and see if everything works.  Observe behavior for several days, make sure all apps work, etc. If everything seems to be working as expected, go ahead and empty trash (if that is where you parked it), or simply delete it from the external drive and empty trash. Be prepared to possibly have to reinstall the OS - just in case - so be sure to make a complete backup before embarking on this.

    Well, I'm stumped as to how/why that folder is where it is; apparently not too many others have encountered that either since there haven't been any other replies. The only thing I can think of is that you inadvertantly drag 'n dropped it from elsewhere and/or it has something to do with where your Hitachi drive parks itself (it that's the case, it should not do that). Does that drive show up where it should in Disk Utility and on the desktop for you to access? If so, then one could safely assume that it is just a duplicate.
