App to Tell Me What's Taking Up Space on Hard Drive?

[mcmike100]

Does anyone know of a program that will tell me how much hard drive space is being taken up by various things?

Recently, I lost three gigs of space for no apparent reason. I suspect it has to do with the cache produced by Lightroom and some other things.

I'd like to find out for sure where that free space went, though.

Any ideas?

Thanks

Finder can do it.

Select View > as List, and Command+J (Show View Options). Select the last button labeled, Calculate All Sizes. Finder will then list all the space taken up by the various apps, files and folders.

Try Whatsize it's great and freeware, you can find it in versiontracker...

Disk inventory X. It really gives you a great idea of what's taking up real space.

OmniDiskSweeper thingy from OmniGroup will do the trick.

I was just using WhatSize. It works quite well and being free makes it even better.

Fire up Terminal

sudo 'du / -m | sort -n -r> filesize;  open filesize'

and you'll get a nice list of files and directories sorted by size (descending).

"find" works well for your task. Use the find command from the terminal.
see "man find" for details.

You can ask "find" for example to print the names of all files larger than a given size. "find / -size +100000000c -print" would print out the files larger than 1000000000 bytes long
Check the find man page for details it can also find files based on other criteria like date of modifation or a pattern in the filename

Of courrse you can hunt around with finder too and click "get info" and it willtell you how big thing are too.
