In both cases, DaisyDisk’s numbers are more accurate, because they are based on physical disk space, and are more useful when you need to find files which actually take up more disk space. (Also note that if you copy a compressed file to another location, it may occupy significantly more disk space, because unlike the original, the copy will not be compressed.)Įxamples of folders with HFS+ compression are some Apple apps: Mail.app, Xcode.app and others. In the latter case, you can significantly save time by selecting the Quick Rescan as Administrator item from the disk’s menu. Use the administrator mode when the scan results reveal significant amounts of hidden disk space. DaisyDisk counts files and folders packed using HFS+ compression by their physical size on disk, while Finder wrongly counts sizes of such files as if they haven’t been compressed. The normal scanning is a little faster, and is enough in most cases. DaisyDisk 4.25, developed by Taras Brizitsky and Oleg Krupnov and a group of translators and contributors, focuses on finding large groups of file clusters, grouping them by size, and offering a quick means of dragging them to a delete icon, getting rid of them, and easily reclaiming your hard drive space. DaisyDisk counts each hard link only once, while Finder wrongly counts each hard link as another copy of the file.Įxamples of folders with many hard links are caches of some Apple apps: ~/Library /Caches /, ~/Library /Caches / and others.įile size and HFS+ compression. It has a great built in feature that bundles up hidden and puregeable space for review and if determined unecessary, you can delete them from within the app.
DAISYDISK SCAN AS ADMINISTRATOR SAFE FULL
You can grant DaisyDisk full access to your disk in System Preferences: go to Security & Privacy tab, select the Privacy tab and add DaisyDisk to the “Full Disk Access” list. On some Macs, when you select the Scan as Administrator command you may get the Failed to scan as Administrator error message.
In case if you deny the access, some folders on the map will appear empty or too small, while the size of the hidden space will grow by the corresponding amount. Troubleshooting scanning as administrator. When you first scan your disk in DaisyDisk, the operating system shows you dialogs asking your permission to access your data, and then remembers your choices. is by default restricted for third-party apps. Starting from macOS Mojave, access to certain privacy-sensitive folders such as Calendar, Photos, Contacts etc.
Sometimes you may find that a folder’s size in DaisyDisk mismatches with Finder’s Get Info figure for the same folder.
