When I click on About this mac and then storage, I see I have 150 GB of Other but only about 50 GB of apps and 50 of music and 50 of photos.....How do i find out what other is so i can delete as much as possible of it?

I was thinking of buying new retina mac book but the 256 flash is very small and before i do i want to see what my total valuable files are in size.

Thanks for pointers.

I have cleared caches in Library and tilde library

MacBook Pro (13-inch Late 2011), OS X Mountain Lion (10.8.4)

    Take a look here: http://pondini.org/OSX/LionStorage.html


    Note that the page may disappear soon.


    Also, it could be that the system has not identified the information. You might try reindexing Spotlight: http://support.apple.com/kb/HT2409

    Hi Barney

    I see you had a look at this dilemma too
    Thank you very much....it seems decidedly odd that i have more of other than i do of anything else.

    I am not quite sure where to begin looking for things to delete because i seem to have at least three libraries and even when i think i have deleted soemthing it wil reappear in some other folder i have never put it in months later. I cant make head or tail out of FInder for some reason. I go round in circles and spend about an hour a night deleting stuff i deleted months ago. 

    Basically i have decided there is no point in a new mac book pro with retina because 256 flash is to all intents and purposes useless. I cant see the point in spending that huge money and having less than a pc laptop did (in terms of storage capacity) 4 years ago. I know its quicker, but i really dont see how any would ever use something so small.

    Tx again Barney

    "Other" file types cover a wide variety of files the system is not otherwise able to easily identify. Many of those are essential to the operation of an application or even the OS itself. If you delete some of those "other" files the system or an application will simply recreate the file the next time it runs. Some, if deleted, will not be recreated and can prevent the system from booting. AFIK there is nothing resembling a comprehensive index of these "other" files and which are essential and which are not. By-the-way there are also a lot of those "other" files that are invisible and you do not see them, likewise there are literally hundreds of thousands embedded in package files that you also do not see in the regular course of business.


    The App Store catalogs well over 100 applications designed to help you in this specific situation. There are so many apps it is a challenge to find what works for you. Search App Store with "disk manager", "disk cleaner". "file manager", etc and your biggest problem is going to be choosing the tool that works best for you. At the moment I am using Daisy Disk but admittedly it took me some time working with it before I learned how to interpret it effectively.


    CAUTION: Before starting any file cleanup operation, be absolutely sure you have a good working backup like Time Machine. It is all too easy to not recognize and delete a file that is essential to the operation of a utility or even the OS. If you are not sure about a file or folder add (disabled) to its name and run for a while before physically deleting it. Look at the date/time of the last update to a file. If it is active you probably do not want to delete it.

    Take a look at OmniDisksweeper or Grand Perspective.

    They will show you what is taking up your space.


    Don't delete anything in system folders.
