This question already has an answer here:

My Mac's disk is almost full. I've tried to delete files and checked out my /var/log but can't find any 'big' files.

What can I do to clean up my Macbook's disk space or to find out what is so huge?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Overig translates to "Remaining," correct? So, does that mean that's how much space is available? Or does Overig translate closer to "Other"? – Kruug Jun 21 '13 at 13:23
I've translated the Dutch bits of the image into English. – Andrew Lott Jun 21 '13 at 13:30

There are two GUI applications for Mac that help visually identify what's taking up disk space: Disk Inventory X and GrandPerspective. If you've ever used KDirStat or WinDirStat then you should be comfortable with it, but even if not it's fairly self-explanatory when you run it.

You can also search by file size in Finder.

Open terminal, run du -s * which lists the total size of all files in each directory.

cd /  # or cd to where you wish to check for large files    
du -s * | sort -nr | more    

Pick large directories to run find on. this find command will list files exceeding 100,000,000 bytes; you can adjust the actual size specified to suit.

# list files with dir directory which are over 100,000,000 bytes
find dir -size +100000000c -ls

Take a look at GrandPerspective. It will show you a map of your files and directories depending on their size, so you can easily guess the location of your big files or directories:

You can download and run a program called CCleaner. It removes all those tiny nasty bug files that build up over time. I try to run it weekly. A mac version is available here.
