I am told by the hd that 120GB are used. I addad up all my files and come to 50GB. On the disc analisis, I have a long yellow bar refering to 50 GB, but I can not locate it. Does anyone know why there is a ghost file of 50GB?


MacBook Pro, Mac OS X (10.7.3)

    Download from the Internet OmniDiskSweeper (free) and open it.  It will show all of your files and the respective sizes.

     

    Ciao.

    Hi Ogel,

    thank you for looking into this matter!!

     

    using OmniDiscSweeper just listed all the files and added them up. It gives 50GB, just the size which I have calculated by hand......but it does not tell me where the f......file is that has 50GB and is listed on my HD.

    My HD tells me I have 120.47 GB used!!  When ODS tells me that I have 50GB on my computer.

    What is going on?

    Look at this link and see if any of the information assists you:

     

    http://pondini.org/OSX/DiskSpace.html

     

    Also you can click on the HDD icon and set 'Calculate Sizes' (Finder, COMMAND 'J'), it will show where where the large files are 'hiding' and should be able to work your way down to them.

     

    Ciao.

    Thank you Ogel.  When I use command-j under Finder, I have only: a little inspector which is Desktop and I can resize icons. It does not allow for 'Calculate size'.

    I am under Lion.

    Any other 'Command (x) under Finder?

    Cheers

    My apologies, I did not give you enough information.  When you open Finder, and when you click on any folder and it is highlited in blue, then you do the COMMAND 'J'. 

     

    Hight light in BLUE example.

    Then you would click on the blue hilited folder COMMAND 'J' and you get this pane:

    You would the check the box 'Calculate all Sizes'.  Depending upon the size of the file it may take a couple of minutes for the calculation to be made.

     

    Ciao.

    Sorry, but my pane does not show calculate all sizes. I wondered where I can chose settings, but in preferences there is no box to activate more choice. command j.jpg

    You're doing the COMMAND-J on a folder found on the Desktop. Since the desktop will always be displayed in icon view, it won't show list view options. Same thing will happen if you do it on folders being displayed in icon view.

     

    As for your problem, download and run the (ancient) Disk Inventory X utility. After it munches thru the info on your drive, it will give you a graphical display of what's eating up the space. Beware, though, that sizes reported by this app may differ from those reported by the Finder; this app calculates space as multiples of 2 (i.e., a MBib = 2^20 = 1,048,576), whereas the Finder calculates it as multiples of 10 (i.e., a MB = 10^6 = 1,000,000). Aside from that, the utility works fine and lets you pinpoint the space gobblers.  http://www.derlien.com/

    Try these steps if Courcouls's advice does not solve your difficulty:

     

    Click on FINDER in the Dock.  That should create the first display in my prior response.

     

    Select a folder and perform a single tap so that the folder is in blue as shown in the prior picture.

     

    Then immediatly execute the COMMAND 'J'

     

    This should result in the display that I have shown.

     

    Ciao.
