Finally a way to know WHAT is actually using ALL THAT SPACE! My wife & I both struggled with internal storage too full to install apps or take more photos  and running that low on storage also seems to cause phone problems in general. While the built-in storage tools is really good at showing you that all your space is gone (duh)  it's not much help in solving the issue. DiskUsage makes it dead simple to narrow down to exactly what folders and files are using that space and even what apps are responsible. Note: DiskUsage does not actually fix your problem or clean up files--it gives you the intel necessary for you to do that. Deciding what to delete and what to move and where to move it is still a bit of a technical exercise that might frustrate a lot of people.
