Storage Management disk usage discrepancy

According to Finder, when I highlight all of my Applications and hit "Get Info" it says only 5.8 GB on disk. However, in "Storage Management" the Applications section says 172 GB (!!!) in use. Can anyone explain what might be going on here?

I think you find your answers in below two images





Rebuild the Spotlight index on your Mac


What is “Other” storage on a Mac, and how can I clean it out?


Free up storage space on your Mac


OmniDiskSweeper Safe to use


GrandPerspective 


How to delete Time Machine snapshots on your Mac


See used and available storage space on your Mac


Locate backups of your iPhone, iPad, and iPod touch


Notation - If the user is using a cloning software like Carbon Copy Cloner - suggest tweaking the Safety Net Feature in this software. It may be making addition Snap Shots that are not being Cloned to the Eternal Drive. If this should be the case, these Snap Shot could be using additional space on the drive

Thanks, I used Grand Perspective and figured it out. Turns out Library/Application Support under my home directory was the culprit. One of my previous applications downloaded a ton of data under there. It seems like the Storage Management app includes that as part of the Application disk usage. The problem is you would never know it because you remove the app and storage stays.
