DESCRIPTION
WhatSize was one of the top selling utilities in the past year on MUPromo. Especially if your Mac starts to get a lot of "stuff" on it, WhatSize helps find out what files are taking up all of that space. Then it makes it really easy to remove or move those files. You'd be surprised how many useless files are lying around on your Mac's hard disk. The files and folders are automatically sorted by size, with the biggest sizes first.
While the app is measuring a folder the user can browse the files within that folder and immediately see the size in bytes. Hidden files, cache files, directories will all show up with their corresponding size. This application is similar to the ancient NeXTSTEP, DarkForest.
Once the measuring of a folder has ended the user can also view the information by filtering for particular file sizes or types. The user can also move unwanted files and folder in the corresponding Trash bin similar to the Finder's Delete button.
WHAT'S NEW
Version 4.7: Release notes not available at developer site nor in download at the time of this posting.

GMANDLER Great product! Love it as I was down to 2G on my Macbook after installing Leopard....in about 10 minutes I found 10G of fat that I no longer needed. I had tried to find these big files in Finder, but WhatSize made it so simple. Love that I can click on a folder and it opens it in Finder for easy delete and trash removal. As for the ratings below I gave the Stability a 4 - but it may well deserve a 5. (Version 4.6) | |

ISTRA Just used it for some minutes. Looks very neat and works intuitively here. • Though, I'm missing a "back" (& forward) arrow... well, maybe some more Finder integration. • in the PieChart view, rather often, the info-beams just clutter. It would be fine to be able to move them around with the mouse, for improving readability. Also, a context menu would be great. Now it's pure graphical. | |

APPLEHC Well, funny little story: WhatSize had some issues with the eSellerate engine they were using. I spent quite a lot of time trying to fix this. The developer could not help so he gave me a refund. Nice - I thought.. Well, today he sent me an eMail that I should update immediately - he may have fixed the problems with the eSellerate engine. Guess what: He just blacklisted my old serial. By testing the new version i got a nice little dialog telling me my serial was blacklisted. Thanks for the genereous help! You have to decide if you invest your money into this software. It is the first time after having bought 200 shareware applications that I completely disagree with a developer about how customers should be treated. I would have bought my licence back if the problem would have been solved properly. But finding myself on a "serial number black list", sorry. Not to mention the update politics.. (Version 4.6) | |

SOLOSAINT this is the only app that allows you to view a list of largest folders by size, grandp and disk inventory x are cool cuz they are free, but this is the best one (Version 4.5.1) | |

JKT Actually, OmniDiskSweeper from omnigroup.com is functionally very similar to WhatSize and has been free since version 1.7 so this isn't the only app that allows you to order folders by size. UI-wise, ODS's looks are a bit dated relative to WhatSize, but it is otherwise almost identical in feature set. (Version 4.6) | |

BRIAN KENDIG Obsolete, now that OmniDiskSweeper is free and does the same exact thing in the same exact way. (Version 4.4.1) | |

SSZYSZKA Wrong. I'm switching from Omni DiskSweeper to this because DiskSweeper is sadly an unreliable disaster on Leopard. Since it's no longer in active development, I am now spending money somewhere else. This is my top contender so far. (Version 4.4.1) | |

SHOCK J While OmniDiskSweeper is a decent (now free) alternative, it does not have the same feature set as WhatSize. (Version 4.4.2) | |

EPRINT This software company wants me to pay for the product twice. Not that the program is bad, but when you see the message, "The unregistered version of this software can measure up to 20 GB of data files. To lift this limit and support a small software development company you will need to purchase a license." I have the license - the screen to enter the number repeatedly indicates i have the wrong number. nicholsr@rochester.rr.com (Version 4.4.1) | |

MACUPDATE ADMIN http://www.id-design.com/software/whatsize/license.php Developer's email address also available at above page. (Version 4.4.1) | |

XENOPHILE So why are you posting this help request here? Email the developer and then you can describe his customer service in your review. Or are you perhaps a mind reader and so already know the developer wants you to pay twice for his software? (Version 4.5.1) | |

ALEXANDRE ACKERMANS Totally overpriced especially since the free Grandperspective application gives a faster, and visually better information about your files. (Version 4.4.1) | |

ERICHLUTZ dont agree, grandperspective is a toy versus whatsize (Version 4.4.1) | |
 | Mar 4 2009 |
MIKELAMBRELLIS Agreed. The visual perspective makes it far easier to see the relative proportions of files and directories versus the total disk size. Scanning is very fast and the latest version provides zooming and other features. For a command line report similar to the GUI output of WhatSize, you can type in the following in terminal: f=/tmp/~sort.tmp;du -hs *>$f;for s in P T G M K B; do cat $f|grep "^..."$s|sort -nr;done (all of that should be on one line) (Version 4.4.2) | |

MIKELAMBRELLIS What I meant to say was I agree with Alexandre - GrandPerspective is better. (Version 4.4.2) | |

I THINK I finally figured out the Problem with the "Serial Name" I DID go back and found my invoice from MacUpdate. I copy and pasted the Name as it was listed there... I THINK (but have not proven) there MIGHT be an invisible "TAB" or two between my First and Last Names. One way or another WhatSize is now working... but after ALL that trouble, it doesn't really offer much as a Utility | |

WICKEDWOUT Same problem here... (Version 4.4.1) | |
 | Dec 8 2008 |
I've tried every variation of my name I can think of... even my company name! Will someone (from WhatSize? or elsewhere) PLEASE solve this mystery?!? | |

JOSMALPEGON I bought MACUPDATE bundle two days ago and the same problem. The only serial left to be received is WHATSIZE. I send an email to the developers so I am expecting for an answer | |
 | Dec 9 2008 |
I asked MacUpdate abouth the trouble too activate my WhatSize. The answer helps me - write your name EXACTLY as you write it when "you" ask for the "packet". I did, and hurray - then it was registrated! This was my way too get it running.. Hope other can use same prosedyre. | |
 | Dec 9 2008 |
WICKEDWOUT Using the exact name you used on the form to MacUpdate works indeed. (Version 4.4.1) | |

SSRMPC Thank you!!! Now it works for me as well. | |
