Disk drive space – that never ending problem – especially for people who do video!
This is one of those little apps that can keep you from having to upgrade your computer just because you need more disk drive space.
File Scanner lets you see your ENTIRE disk drive… ALL OF IT… at a single glance.
It uses a graphing technique pioneered at the University of Maryland called Tree Maps. They way they work is they can show hierarchy (like file folders being nested), size, and finally the color can mean something too.
But what I like about Tree Maps is it allows me to see my entire disk drive, find the biggest files, find the biggest directories and then take action – usually deleting wasteful space hogs. I've often used this technique to prevent having to buy more space.
Disk Drive Space at a Glance
Here is a picture of my disk drive. The BIG colored squares are files. The bigger the square the bigger the file and you only want to work on BIG files so you time is effective. The black rectangle is free space and the gray area is other users files which I don't have permission to see. If you look, you'll see that you can see the groupings of files representing a folder of information.
You can zoom in on sections in the colored area to gain additional detail. If you are ONLY interested in a small section of your drive, you can scan that section only.
I've tested this disk drive space visualization software against several different apps offered off of Apple's Mac App store but this one is the best. Its advantages are:
- Builds off of the open source project “Disk Inventory X” which seemed to stop in 2012
- Extremely fast – 2-3x faster than others I tried.
- Allows you to see your free space and other uses spaces so you get the entire drive
I love this application and I use it all the time.
