During a backup last week I noticed that my Mac had almost 1.5-million files, each of which was dutifully copied from my Mac to the backup disk. I thought, ‘Surely out of all those files there must be some I don’t really need.’ There were. Here’s how I found them.
Diagnosing The Disk
My Mac is carefully pruned and curated, when files organized neatly into the Documents folder, plus the usually array of photos in Pictures, songs and TV shows in Music, and video clips in Movies.
I was pretty sure the files I manage on my Mac didn’t account for the bulk of the 1.5-million files, so where did they come from?
Disk Diag was the app I used to dig around, discover, and clean up a few hundred thousand files I didn’t really need.
This free Mac utility comes with seven basic modules to clean up files on your Mac that you didn’t even know existed.
Some of the modules are obvious, like Downloads (which I normally prune), and Trash (which I delete from time to time.
The other five are modules which combine to find and get rid of caches and logs, browser data, and other files which are stored on the Mac but unneeded.
Disk Diag is made for Mac users who don’t want to get their fingers dirty while perusing through cache files or running Apple’s built-in OS X scripts (which need to run overnight to clean out caches).
Open Disk Diag and let it run to see what it finds. Chances are good that four or five of the built-in modules will find files that need to be deleted. Click to take a look at what’s there, and click Delete Files to have them removed.
When Disk Diag is done it will list the total amount of files that were removed. It’s a quick, painless, easy, and free way to add a few extra gigabytes to your file space. Thousands of four and five star reviews for this handy little app.
