I have noticed recently my MacBook Pro had been very close to running out of Hard Drive space. I knew software existed that would show me where the space was been used the most. Thanks to twitter and the following tweeters @rasga, @dachande663 & @podnosh I found Disk Inventory X.
Once you download and install the app you highlight the disk you want to check and then select ‘Open volume’.
The app will then scan your drive and calculate the size of every file/folder and display it in the following view. You can then drill down and see where your hard drive space is been used. You can then move files to the trash to free up space if you don’t need the files anymore.
Thanks to the above application i’ve gone from 6GB available to 52Gb. Very handy!
