Sweep your Mac clean
Mac Tip #364, 12 November 2008
When I did a sweep of my MacBook Pro recently I recovered 10 gigabytes of space lost to some unexpected hidden files.
Because the files were hidden — their names began with a dot — of course I had no idea they were there. I was just mystified that free space on my hard drive seemed to have disappeared.
How I found the wasteful files.
I downloaded a small piece of software called OmniDiskSweeper and set it to run. OmniDiskSweeper is free, but
US$15 activates a handy Delete button that can save you some time later. [Update: in 2009 the full version was released free.]
It took a while, but after several minutes OmniDiskSweeper produced a listing of all files and folders on my Mac, with sizes beside each.
I quickly saw that Users > Miraz claimed around 60 Gb of space. Then I clicked on Music > iTunes > Podcasts.
I saw that the Rocketboom podcast was using around 840Mb of space — odd since I’d deleted all the episodes I’d watched and there were none waiting for me.
Then I spotted it: the .indelible-info folder that contained a bunch of items inside a folder called deleted. I could see podcast episodes dating back many months, all of which I thought I’d removed from my computer.
When I first examined my hard drive a few weeks ago I found a lot of these .indelible-info folders. By removing most of them I reclaimed nearly 10% of the space.
Warning: don’t delete files unless you know for sure what they are. The Operating System hides some files for good reason — delete the wrong files and you can severely mess up your computer.
Try a sweep of your Mac and see what it turns up.

I recently came across your blog and have been reading along. I thought I would leave my first comment. I don’t know what to say except that I have enjoyed reading. Nice blog. I will keep visiting this blog very often.

Miraz, as far as I can tell that .indelible-info folder is a result of unclean shutdowns… can’t find any on my machine. Worth knowing about that app, but hopefully (!) that won’t be a common problem.
Thanks for that elucidation Andy.
I have had problems with this machine crashing, so wouldn’t be surprised to find there are stray files.
I plan to wipe this machine over the summer holiday and start fresh.
Cheers,
Miraz
