  Is this app still free?

  Is this app still free?? It would be a bargain at any price. I have used it for years but today it became worth every bit and byte in gold! I have had a samsung 1 TB SS drive with 770 gig stuck in the trash. I had done everything I could find on the web to empty the trash including using some terminal commands that scared the hell out of me. Nothing worked. I was getting ready to wipe the disk and lose some files on it that I needed to keep. But then it occured to me to scan the disk with Daisy. Low and behold I could visually see the 770gig that was stuck it the trash. I dragged the file to the delate tab and pushed "delete"! Whalah! I recoupped 770gig with my essential files intact! From now on this is my go to app for recovering disk space. Fan for life!!!!!!

  I love this app!

  I’ve used Daisy Disk since early 2013, and it is a delight: visually appealing, and an extremely effective way of finding and removing clutter on your computer, or identifying space hogs that might be candidates for optimizing. If you care about that sort of thing (and I understand if you don’t), this is a superb tool, and well worth the price. UPDATE October 2018: from 5 stars to 2. Disk Xray Lite lacks the visual appeal, but is free and 10-15X faster at scanning large directories (which in my case are not even that large: <90 GB). UPDATE November 2018: I appreciate the developer’s response, which I received by email (don’t know where to find it here). I did another test: Daisy Disk scanned my entire home directory in 48 seconds; Disk Xray Lite in 08 seconds (OK, only 6X faster). The latter is also visual, despite what the developers of Daisy Disk imply, and in fact while not as pretty, it is actually easier to visualize file sizes because they display as horizontal bars. I’m pretty sure the human brain is better equipped to compare the size of bars oriented in one direction to “pie slices” all oriented in different directions.

  Difficult to use for larger disks

  I have a 3 TB fusion drive and, although I only have 500 GB used, I still want to see what is taking up space. In this configuration, a 15 GB directory on the fourth level of the ring is so small it's difficult to get the mouse to hover over it. There are two things this app could do to be more useful for me. First, it could add a toggle to exclude free space from the ring, so the 500 GB of used space I currently have takes the entire circumference. Secondly, the ability to scroll/zoom in would be useful as well. Some view preferences in general would not go amiss. The app looks very nice, but the above and its complete lack of configuration make it mostly useless for me. Edit: I have noticed the ability to click on a section in a ring to effectively zoom in on this area. I am increasing my rating, but still deducting a star because I think this is a bit unintuitive.

  Takes itself too seriously

  It acted like it was infallible and if I purchased the license key it would be able to detect the hidden files. It never faltered in its confidence - "buy and you will see the hidden files.” I purchased and it only then sheepishly admitted it had no idea where the files were, and sent me to a checklist to manually review. I manually reviewed every item in the checklist, and not a single one helped. The final one was to contact support, I have done so and I am asking for a refund. I am infuriated that I just wasted my time and money on this app because it had such a pompous attitude up front. Every other app was transparent about how it couldn’t find my files, so I didn’t bother purchasing them. This one put on an act, and pretended it could be useful, just to waste my time, and that is unforgivable. It could have told me up front that the files where unfindable. I should not have had to purchase to find out that the program is broken. This is an editor’s choice? What a rigged system the app store is.

  DaisyDisk saved me a lot of time

  Due to a mis-configured backup I had 3TB of hidden system files on my Windows that were making the computer unusably slow. DaisyDisk let me see the files, and then its free add-on license for the direct download version with Administrator features let me access and delete them. Before DaisyDisk my choices were pretty much format the HDD or buy a new computer as my current Fusion drive is about 5 years old. DaisyDisk's excellent documentaiton showed me how to run diagonistics on my Fusion drive and determine it was operating without errors and no need for new hardware at this point. Great value for money considering the time DaisyDisk saved, and I recommend you try it to get a better understanding prior to spending time or money on other solutions.
