Disk Map: Visualize Disk Usage 4+

On a fast Macbook Pro with solid state drive, the software performs very quickly at scanning almost 1.8 million files - less than a minute. The resulting display is attractive and intuitively useful for quickly identifying the disk hogs. (I didn’t know that Outlook files and their archives were taking more than 30Gb of drive space, for example.) The software offers basic tools for compressing and deleting files.

However it’s missing a glaring - IMO - requirement and has a few other niggling shortcomings. The disk map displays in a relatively pint-sized window on a 15-inch display, and on my busy system it isn’t nearly big enough for useful information. The map window doesn’t have the maximize icon in the upper right; it must be dragged to fill the screen, and the software doesn’t remember the size at which you last used it. Nor is there an option in Preferences to specify that it should always display the map full-screen. I’ve used it twice and already annoyed at having to manually re-size the map display.

Further niggles: the software doesn’t remember the folder or drive you last scanned, you have to tell it each time what you want to scan, which may often be the same drive/folder as last time, and the software requires a couple more clicks on a Next button than should be required to do the obvious task… just display my last scan location and let me click once to get to work.

After buying and trying to open this app, I get the message '"Disk Map.app" is damaged and can't be opened. Delete "Disk Map.app" and download it again from the App Store.' - but doing that produces the same result - on a mac M1, MacOS 11.4 Big Sur. - seems this is not ready for a Mac M1.

it is very easy to use, and obvious to see and understand the breakdown of your computer, highly recommended!
