Disk Inventory X

ABANDONWARE. The developer's site is no longer available. The software hadn't been updated since 2019 in any case. There is no chance of it being updated for M1 or M2 ARM. Instead, I use DaisyDisk or GrandPerspective. Less functional but useful utilities are OmniDiskSweeper and WhatSize. You'll see other options on the right side of this page.

Absolutely useful little app. Simply the best of its kind.

Been a happy Inventory X user for 15 years - incredibly useful at spotting those space hogging files that you'd completely forgotten about! I don't get the negative reviews at all - anyone who knows how to use this properly likely finds it indispensable at some point or other... thanks derlien (the developers)

I think it's immensely frustrating. I read all of the reviews saying how handy it is, and I can't make it do one darn thing. How does one get help around this place or find out how to use this thing?

Version 1.2 corrects the comma formatting issue. This application is indispensable to me.

Nice to find big files and memory leaks )

Download link on MacUpdate is broken, here is the correct one: http://www.derlien.com/download.php?file=DiskInventoryX

Great app - you can trash it from the drop down list, unless it needs permissions, in which case you can 'see in finder'. It's great for looking at the whole disk or just a folder - I use it to track down wastes of space, but it's also helpful for me to find folders and files in "Library" and "Application Support" that I, a noob, simply cannot find otherwise. Thanks Tjark for the good app

Highly reccommended to check your drive for files taking up space. This software made it easy for me to localize a lot of huge files that I did not need any more.

Disk Inventory X is the best of both worlds, giving you both text listings of files and folders as well as graphical representations. The only feature I can recommend would be the ability to select multiple files within a folder for deletion.

Written too much today to be too erudite. Lots of great easy-to-use features here though the treemap and icon ARE ugly. Customizeable colors would be a start. An update with Quick-Look integration would be brilliant!

This was an invaluable tool for me to find a hidden volume of old video crap (75 gigs!) and delete it. Thanks for freeing up my hard drive to process everything!

For anyone who comes from OS 9 and has used disk surveyor in the past, this app is a bit confusing graphically (only files are displayed graphically, and not folders sadly). I have also used an app called Disk Sweeper which I thought was more intuitive, and Grand Perspective which I thought was faster to load and used less CPU.

doesn't get much easier than this...seriously. I used it, and 20 minutes later have cleared 20GB away of *stuff*.

excellent little app...though it needs a cooler looking icon :)

This app is superb! It's amazing how something so simple can be so jaw-droppingly useful... I freed up 6GB on my 40GB iBook the first time I ran it, on superfluous spuff that I didn't have any idea was eating up that much room. This app is a "must have".

Ever felt the need to know where your disk space is going? Having been a faithful user of SpaceMonger for Windows, I've been on a lookout for similar tools on other platforms and this is a stiled-up version for OSX: It lets you uncover how iLife and GarageBand is filling up your hard drive and how old iPhoto-catalogs are claiming gigabytes. I can but recommend this program. If you make it a part of your Mac life, consider donating.

Universal Intel version available as beta at: "http://www.derlien.com/dixforum/viewtopic.php?t=62"

This program is a GODSEND! I can't believe it is free. And it is GORGEOUS! Seriously, this program is the absolute best way to see what is taking up space on your HD. It works wonderfully/amazingly/beautifully. I am happy to have it. It is my friend. Thank you. OH, and the plugin idea works perfectly (gives you right click support to see the graphical contents of a folder). In the prefences menu, there is a button to install the plugin if you want it, and a button if you want to uninstall the plugin. Right-click saves me that much more time. I love it.
