If you like GrandPerspective then you might also be interested in Disk Inventory X and WhatSize. It’s a fantastically quick and intuitive way to find those giant files that are sucking up your disk space. GrandPerspective has a few other features and options, but overall it’s a simple app that does one job well. If you want to find out the sizes of enclosing folders rather than individual files, use the Focus buttons in the toolbar to change folder levels (or press Command-). Also, should you so desire, you can zoom in on really small files by using the Zoom buttons in the toolbar, or by pressing Command-+ (plus) or Command- – (minus): If the view is all a bit overwhelming, you can click the Edit button in the Display tab to display only certain types or sizes of files. You can change this by clicking the Drawer icon, then the Display tab, and choosing an option for Color by: By default, files in the same folder are given the same colour. Rectangles are grouped together by folder, making it easy to find stuff in the same folder. Deleting is disabled by default (it’s easy to delete more than you mean to), but you can enable it in the prefs. Click a file to select it, then you can open it or reveal it in the Finder using the toolbar buttons. You can see that my Parallels Windows XP virtual hard disk is taking up the most space, at 9.53 GB. Hover over a rectangle to see the file name and size in the status bar. The bigger the rectangle, the bigger the file. Windows users can use TreeSize to find large items and folders, but it doesn’t deliver the same visual display. GrandPerspective is a free download for Mac users. Here are all the files on my hard disk:Įach file is represented by a rectangle. If you mouse over the block you will see the name of the file type and if you right click, you can open in finder so that you can review, move or delete the file. You then see a visual representation of all the files. Check the System Memory tab in Activity Monitor to check page outs and swap used. You can choose a folder, or click your hard disk icon to scan the whole disk:Ĭlick Scan, and GrandPerspective reads all the files and folders (including subfolders) in your selected folder – this can take a few minutes. Check to see if some of the space is being used by your sleepimage file. Each file is shown as a rectangle with an area proportional to the files size. It uses a so-called treemap for visualization. It can help you manage your disk, as you can easily spot which files and folders take up the most space. When you open the app it asks you for a folder to scan. GrandPerspective is a small utility application for macOS that graphically shows the disk usage within a file system. GrandPerspective is a free app that gives you a graphical representation of all the files and folders on your hard drive (or in a specified folder), using a clever technique known as treemaps. However, I recently came across a better way to find big files. Obviously deleting a few big files is less effort, which is why this Finder trick is useful. That meant I needed to delete some files – either a lot of small files, or a few big ones. I recently ran out of disk space on my iMac (I regret buying the 250GB hard drive model and not the 500GB!).
