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.

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

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.

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.

J'ai testé l'application DaisyDisk sur mon ancien Macbook pro (mi-d-2012) dont le système High Seirra 10.13.1 est installé. DaisyDisk démarre rapidement avec le système et il ne ralentit si pas le CPU ni le RAM de mon Macbook. Le design ainsi l'interface de l'application DaisyDisk permettant d'avoir une décomposition visuelle de votre espace disque sous la forme d'une carte interactive, de révéler les plus gros gaspilleurs d'espace, et de les retirer avec un simple glisser-déposer. Les options de l'application sont multiples mais ce que j'ai aime beaucoup le plus : c'est l'option dans le menu qui te permettre se découvrez ce qui se cache dans la catégorie "Autre" et de l'effacer. Aussi il te permet de récupérer de l'espace disque en trouvant et en supprimant de gros fichiers inutiles. À la fin de mon test-je donne 5 étoiles et je recommande vivement l'achat de cette application
