DESCRIPTION
DaisyDisk ... Visualize your disk and free up disk space by quickly finding and deleting big, useless files.

The program scans a disk and displays its content as a sector diagram where the biggest files and folders at once become obvious. To drill down to a folder, just click on a segment. To bubble up, click in the center. Move the mouse over the diagram and see the name and path of each file, and enclosed files (if any). Hit Space to quickly preview file content, without launching another application. Ctrl-click to open a file in Finder.

WHAT'S NEW
Version 1.3.6:
  • Added the base-10 math for calculating file sizes on Snow Leopard (10.6), to match the file sizes shown by Finder
  • Minor fixes and tweaks
REQUIREMENTS
Mac OS X 10.5 or later.

ICONZ113  That sample photo in the description, is that the only view you get for each drive analysis? is there a way to identify what is what?

JAZZJOHANNES  Another possible feature:

Saving of snapshots and space efficiency comparisons.

DAISYDISK  So far we avoided dealing with snapshots as these often take hundreds of megabytes of disk space. Unlike some competing products DaisyDisk never fills your drives with garbage…

From another point we do understand this feature may be useful, so we'll try some options in experimental builds. If they prove being effective, then comparison feature may be added to DaisyDisk as an option. But that's all after version 1.5 we're working on now.

E_COMMERCE  I would second the option of creating such reports as needed, as I frequently find myself scratching my head saying "I know I had 10GB more space a couple months ago, but I don't see any single spot where it went". Being able to compare past and present would be very useful in such scenarios.

STILL_SPARKLING  Daisy Disk really has no peer in drive visualization, so you can pretty much ignore the suggestions for similar apps. The gorgeous UI, speed, and stability make it a pleasure to use. Add to that the stellar customer support from the developers and you have a real winner.

Yes there are other apps that can do the same thing, but DaisyDisk's method of color-coding each area of your drive is so fluid and intuitive, you won't want to use anything else. It makes getting rid of space hogging apps and files a breeze.

The are two things I don't like:

1. The price. I think it should be at least $5.00 cheaper.

2. The fact that it isn't built into Leopard automatically. Come on, Apple -- add this puppy to Snow Leopard!

DEMORAY  I like DaisyDisk. It's a polished little utility with an attractive interface. But for you to state that there are no worthy alternatives is a bit disingenuous.

GrandPerspective is a free alternative that offers customizable color-coding, and uses a slightly different way to graphically display the files on your system. I actually prefer this graphic display method over the pie-chart that DaisyDisk uses.

WhatSize is a very nice shareware alternative that offers FIVE different display methods to chose from, including the pie-chart, bar-chart and table views.

Once again, DaisyDisk is a great app, but it's certainly not the only good choice.

JAZZJOHANNES  Bravo, wonderfully useful software!!

The snappiness of interaction is remarkable!

Suggestion: Outdated / long time not accessed files filtering, perhaps diagrammatically represent the timeline with lines (long, short etc.)

It seriously is a huge step forward in computer management.

Thanks a lot.

DON MORRIS  Dang! I so want to buy this. However, I'm bugged by several things:

- No hierarchal column or list view. Leaving out the way most people view files is a serious shortcoming.

- (Smaller files and folders). I really want to see what those are, sometimes. If I hover the mouse pointer over that very narrow strip I'll get a list, but I can't do anything with the items in the list.

- Can't drill down into every folder. If there's a folder in the "smaller files and folders," I can't see what's in it.

These all boil down to "I can't see every file on my disk."

DAISYDISK  Greetings, Don

I'm Taras, user interface specialist behind DaisyDisk.

There're definitely some usability issues related to "smaller files…". They're not perfect, but proved being a very effective way of reducing information noise. In practice dealing with this item, representing collections of small or equally sized objects is often useless because it requires too much micromanagement (example: a set of 1000 photos plus some icons and text files) we're trying to avoid. It also mostly distracts one from the main goal: free up some space (not "just wipe out files I don't realy need"). Make sure I'll recall this question the next time we start the next big round of sunburst improvements ;)

And don't forget that DaisyDisk is not a file manager and has never been positioned as such.

DRDUL  Daisy Disk has the best UI of these types of apps. Easier to understand, easier to navigate and easier to see details. Quick Look integration is great! The only things holding me back from buying a licence are:

• Inability to delete files directly from Daisy Disk

• Graphic doesn't display as large as possible within the DD window, which means it's sometimes difficult to see details

• Inability to set a (slightly) larger font size

This is an app with lots of potential. I'll be keeping an eye on DD as it develops.

DRDUL  To clarify my earlier comment, where the font size is particularly an issue for me is the file path displayed at top right. The other fonts are small but legible, whereas I can barely see the file path. Perhaps a status bar or some other way of displaying the file path would provide more space to use a larger font?

Also, i should have added the suggestion of undo capability with a file delete feature. Sure, i can always restore the file from the trash (which will be easier with the "put back" feature in Snow leopard), but that means I have to be able to remember which file(s) I deleted. Undo capability within DD would be an essential part of a file delete feature.

DAISYDISK  Greetings, DRDUL.

Direct file deletion is planned. As you may notice, it's not easy to make file deletion easy and comfortable for all situations from local files to remote servers without giving one a perfect "mess my data" tool (error-proof is one of such). We think we have a good solution and it will definitely appear in future versions.

We've already thought of some further display optimizations. If our experiments succeed, you'll see some of these changes in the nearest future. We usually tweak map display a little each release :)

As for font size, feel free to tell us more about the issue. Write to support and I'll definitely pay close attention to this problem.

CORPSECORPS  While it would be nice if this could delete files, the UI is so slick and gives one such a clear immediate concept of what's gobbling space where, it's brilliant.

Scans disks quickly appears to be very solid. Bought it on promo, but after using it more, i think it's worth full price...almost. 8^)

GRYFFIN  PROS: Visually stunning, polished animation, innovative display concept; I prefer graphical tools for this sort of thing. Preview feature is a nice addition, but crashed the app on some files.

CONS: Main graphic seems too small, even on a big monitor; negative space is nice and all, but I'd prefer if DD displayed its info graphic as large as possible. Also, DD has no ability to trash files itself — MAJOR omission. Also, costs $$$ in a field full of free alternatives.

COMPARISONS: WhatSize and OmniDiskSweer use a text-only approach that's fast and simple, but as I said above, I feel a graphic representation is more intuitive than a hierarchical list of folder/file sizes. GrandPerspective has nice graphics, but it's harder to navigate, and harder to get a good "big picture" view, and really needs a hierarchical list. DiskInventoryX is still the one to beat IMHO: similar graphic display as GrandPerspective, but it also has a hierarchical view — best of both worlds!

DJEFIS  Spectacular!

This is the Application***** that can shows the new Frontiers related at the Finder Evolution . . . .

I hope that, in some characteristic, its genial Interpretation related to the management of the content of the HDD will be not underestimated!

Thanks at the Developers, Maurizio.
