DaisyDisk 4.21.2
The link for WinZip (for Windows users) or Stuffit Expander (for Mac users). Both are free downloads. Once you have done that, click on the version of Statdisk that corresponds to your machine. I have Windows, so I selected the first link. That presents you with a Save As dialog box. Choose where you want to save it and click OK. A single app for different cloud storage services. We're now downloading Dropbox. When your download is complete, run the Dropbox installer.
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.
