Way back in the day, back before Mac OS X, back when hard disk drives were expensive, loud, and not as large as today’s models, we Mac users had to scrimp and save on disk space, otherwise, we’d end up with more files than the Mac had space to store.
Then came the glory years of storage; those years where are disk drives were (and remain) huge and yet inexpensive on a per gigabyte basis; those years where we never ever had to delete a file because, well, you know; lots of inexpensive storage space on massive hard disk drives.
All trends change, and Macs today come with solid state disks (SSDs) which are much faster, less prone to crashing, more expensive, and have less storage capacity that typical hard disk drives. For example, Mac users can find 2TB disk drives for less than $100, while a comparable SSD goes for about $600.
All of a sudden we Mac users are required to pay attention to storage limits again.
Enter Disk Expert, a useful Mac utility which scans your Mac’s storage– SSD or HD, internal or external– and give you a list of which files are hogging up the most space, including hidden files, the largest files, and how much free space remains on your Mac. Files on your Mac are displayed in a clever graphic wheel so you can click and zero in on offending fat files.
Disk Expert can scan almost any storage connected to your Mac, including SSDs, HDDs, removable USB drives, SMB disk images, CDs, DVDs, and mounted disk images. What you get is a fast scan and a quick way to view available free space and which files are taking up the most space.
Alright, so you find files that take up more space than you think they should? Now what? Disk Expert lets you drill down into folders and view files in QuickLook, so you can see which files are valuable and should remain and which are less valuable and can be moved or stored elsewhere.
Here’s the only real problem I have with disk storage scanner apps. They scan every file, and that’s good. They list the largest files, and that’s good. What they don’t do is tell you which files can be moved or deleted. That would be nice to know. Otherwise, Disk Expert doesn’t cost much, and easily can help you find large files you don’t need (so long as you know you don’t need them), and makes it easy to delete them.
