DaisyDisk is a sensational visual application for those of us that like to keep track of what we are storing, how much we are storing, and where we are storing files on our machines.

This week, we are giving away 20 free copies of DaisyDisk worth $400 to some very lucky winners. In addition to the 20 copies, we also have a 25% discount code for those who are looking to purchase the app themselves. Both the giveaway and the discount code offer expires on Saturday so you can decide which route you wish to take.

I am really captivated by the simplicity of the program and the colorful display. Below is the only screen you will see when you boot up the program indicating what is available to be scanned.

Once you select a drive, the scan process takes about a minute depending on how many files you have in the drive.


After DaisyDisk scans your drive, you get a colorful graphic that illustrates where your computer is storing files and what types of files are being stored.  In the example below, I can see that “User” (me) uses the most space.  If I shared the computer with a coworker or with my children or spouse, I could see which one of us used more space.

If I click on “User,” I can drill down to see how the space is being used. Space usage is symbolised by the area being taken up — the larger a section, the more space is occupied. Not surprisingly, music takes up most of the space.  If I want to return to the previous level, I can simply click on the center black circle to go back one layer at a time.

If I want to continue drilling down, I can see that all of my music is housed in the iTunes folder.

If I want to break down music according to artist or theme, I can drill down another level. Of course, this all depends on your iTunes organisational structure since DaisyDisk only takes the folder size into account.

You can keep drilling down until you have exhausted the search.  While it is great to know that these files exist, DaisyDisk also helps you clean them up.  Simply right click on an item and choose “Preview”  from the menu to first check what the file is.

Then return to DaisyDisk, select “Show in Finder” and it will take you right to where the file is stored. If you don’t need it, trash it.

DaisyDisk allows you to visualise what takes up the biggest amount of space, and helps guide you to delete large unwanted files.

So here I am on my new team, a single Mac IT guy to support thousands of Mac users that did make it past the acquisition and all my new Windows users. I'd love to add DaisyDisk to my arsenal of tools not only to show off how functional Macs are, but also to show how functional I am. Makeuseof please make use of me!

    I would like to win a copy of DaisyDisk in the giveaway for the following reasons:
    1. I am a college student and I need to save a lot of notes and make quite a few presentations. This, coupled with audio and video recordings of my classes eats up my disk space quite easily. I would like to know where the heavyweight junk files are lurking on my Mac so I can delete them.
    2. I love taking pictures, so my hard drive tends to fill up a lot every time I transfer pictures to my computer. Again, I would like to know where most of my space is being used to I can deal with it effectively.

    This article reminded me that my MacBook Pro was low on disk space (25GB free on a 160GB drive). So I ran it and it showed me that my Trash was taking up a lot of space.I also found a few big files and emptied out my Downloads folder. I managed to free up 50GB between the Trash (66k items in less than a year!) and other files! No joke. (I got this in a MacHeist nanoBundle if my memory serves me.)

    I am forever downloading files and then "losing" them on my Mac; sometimes I find files or apps I have downloaded that I no longer even recognize what they are.

    I would love to use a program such as this that can not only help me find them easily, but help me decide what to keep and what to trash- I need all the help I can get!

    Recently did a reformat/rebuild of system. So much time was spent sifting through files, eliminating storage hogs, redundancies, before I could even start to perform the backup. Looks like this could have helped immensely.

    Here's a similar freebie I've been using for years, for those that don't win a 'Daisy'.

    I just recently became a Mac user. The campus where I work is seeing an increasing influx of Macs and we have broadened our service to support them as well as PCs.

    As a result, I'm always on the hunt for new and/or interesting Mac apps, both to help me with my learning curve on the Mac as for suggestions of good software to pass on to the end users I support.

    Cheers! and thanks.

    I used to use a similar tool when I was on windows. This would be great to have on the Mac
