Free up disk space by quickly finding and deleting big, useless files.

Overview

DaisyDisk allows you to visualize your disk usage and free up disk space by quickly finding and deleting big unused files.

The program scans your 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. In this way, walk around your disk and drag-and-drop all unneeded files into the "collector". Expand the collector to check its contents. When done, clean it up with a single click.

What's new in DaisyDisk

Version 4.10:
  • DaisyDisk now scans the local snapshots of the APFS file system and displays them inside the "hidden space" area. Now it’s much easier to deal with the hidden space, because the snapshots are often its largest component.
  • You can now delete the snapshots by simple drag-and-drop, as with regular files.
  • Added "Open in Terminal" context menu command.
  • Minor improvements and bug fixes.

This is one of those apps that might make you think to yourself as you use it, "Why don't all apps work like this?" I really don't have a serious criticism to offer. Very intuitive, fast, even helps you take the garbage out to the curb. My only caution would be to second the advice from an earlier reviewer to get the non-MAS version as it is more complete (It has safeguards against deleting critical system etc files so no worries.) That version also gives you a trial option. If you try it you'll buy it IMO. Top notch utility

v 4.10 still can't scan the data partition of my boot volume. Grand Perspective CAN! Wha't keeping DD? DD also returns incomplete results for a clone I maintain in the same container as my boot volume. Newly improved, though, DD gives me complete results for my clone in another container. (Is there a way to get paragraph breaks in my posts?)

This is an excellent app, with a bonzo interface. I've used it for years. It has kept up with changes in the macOS, which is remarkable in itself, when so many of the apps I use have been abandoned. In particular I used it to find the large sleep image files that were eating up space on my small startup partitions. I finally learned how to prevent the creation of those files, but it took a while for the solution to turn up. Not only does DD show you your files, but it enables you to locate them (until APSF started hiding stuff more securely). There are other apps that show your files, like GrandPerspective, but I think DD is superior.

v 4.9 still cannot see the data portion of a System/Data pair. Grand Perspective has no such problems, so what's wrong with DD?

I won't give DD a star review, because although I'm pretty sure that what I'm about to complain about is its fault, it may be an inherent problem with Catalina...or it may be a combo of the two. DD is unable to see Catalina's system & data volumes as a complete unit, even my boot volume, so it doesn't find, at the least, /Library. GrandPerspective doesn't find everything in my clones, but it does find everything in my boot volume. Happily, I got DD on sale for only $5.

Apple completely changed how Catalina sets up the boot disk; the system is kept in a separate 'read only' volume, and user data on another volume, both under one APFS container. This was to protect system files from modification. Read here: https://www.macworld.com/article/3451363/why-you-might-see-a-new-data-disk-in-catalina.html Open up Disk Utility and take a look. Apple does some trickery with mapping and symbolic links so that in Finder it all looks like one volume. Older software that read disks (like DD) that are not updated for Catalina compatiblity may see two volumes or may see it as one. Daisy Disk 3.0.3 sees the System and Data volumes as separate. Daisy Disk 4.8.2 and 4.9, see everything combined as one volume, being updated for Catalina compatibility. I don't know about earlier versions of DD 4. I suspect you are using DD 3 or an earlier version of DD4 prior to Catalina.

This 5 star rating is to help offset the 1 star rating posted on Mar 17, 2019. I donl't believe that the user who posted that review understood that one can 'drill down' through the folder structure until each individual file is as large a section of the pie as you want. As for whether a pie display is the most efficient...well given that the average macOS disk has literally MILLIONS of files, I think the graphical display is the only way to go. Navigating a traditional Finder List View doesn't give you the instant feedback that pie section gives you regards relative size of a file compared to files around it and above it in the hierarchy. To each his own. I've tried all the 'file and disk size comparision' apps; this one is the best and very quick response when navigating.

DaisyDisk Has been the Gold Standard for visual drive exploration. Please note that you can now do this with CleanMyMac X and other applications, but Daisy Disk has a certain "Aroma and Grace" that you just can't beat.

I don't know why this app is so famous? Because the FIRST one app is using a Pie Chart? I won't buy it again, if someday an upgrade needs to pay. Reasons: 1. A pie chart is so beautiful, but it's not a good solution. Especially there are a few small pieces, because your cursor is very hard to touch this small pieces to show the information. 2. Now, there are a lot of apps about Disk, and they are also using a Pie Chart, and their price are cheaper or free. Thanks.

The developer writing here. DaisyDisk uses a special kind of visualization that is called "tree pie" or "sunburst". You can think of it as a tree-like pie chart, where each slice is a "child" pie chart in itself. On early stages of our design process we analyzed and tested all existing kinds of charts for visualizaing file systems and concluded that the tree pie works best in most cases for most people. The tree pie was invented long before DaisyDisk, but in order to achieve its real efficiency, we came up with a multitude of our original enhancements that drastically improved readability and navigabilty of the tree pie chart. In particular, we sorted segments, reduced visual noise, added navigational colors and animations etc. Also we introduced the two-panel design that adds a lot of contextual information without cluttering the main view. Before DaisyDisk tree maps were a nightmare to use, now all apps of this kind copy our design :) Now let me comment on your reasons: 1. The point is that you're looking for big files, small files are not important for the purpose of freeing up space, so they are deliberately made small, low contrast or removed from view altogether, as visual noise. 2. There are a lot of apps in this category, but unfortunately they are either poorly designed and a pain to use or low-quality knockoffs of DaisyDisk. No other developers invested so much time and effort in the easy & comfortable user experience as we did, and our price is very moderate. I'm proud that DaisyDisk is now the most popular app in its category, it has won "Best of the Mac App Store" three times and all major media titles have written editorial reviews of DaisyDiks (there are over 500 publications in total). No other app can boast that.

Impressed with the app, provided an excellent visual on data/area I was trying to see. One question I asked the developer was responded back by very quickly.
