Even though we reviewed WhatSize before, I didn’t realize it’s usefulness until now, when my hard drive started acting up. I was browsing through my folders in the Finder, and saw that the “space remaining” on my hard drive was shrinking by the second. It went from 50 GB free, to about 64 MB free in about five minutes. I didn’t know what to do, and I thought I would have to wipe my hard drive to fix the problem. I didn’t want to have to back up and reinstall OS X, as that was a last resort. I remembered MacApper’s review of WhatSize, from ID-Design, and immediately downloaded the app.
I wanted to figure out what was using up all my space, so I ran WhatSize. Everything looked normal, until I found that my Library folder was taking up gigabytes upon gigabytes of space. Looking into that folder, I found that my Logs folder was over 40 GB in size. I trashed it, and my space was restored. I’m not sure why my logs suddenly decided to increase in size, but WhatSize helped me find the problem, and in the end, save hours of backing up, reinstalling, and restoring files.
