Did you ever wonder what would happen if a game studio wrote a disk scanner using its game engine? Wonder no more. Introducing Disk Falcon, our unique, futuristic disk-scanning utility. Based on highly acclaimed game engine used in "Ultraviolet Dawn", Disk Falcon shines with the polish of over three years of engine development and testing, with its user interface being almost entire animated in real-time. The scan results can be broken down by individual files, file types, or ages, and presented in either doughnut or bar chart (and, of course, these animate as well while the scan is ongoing). Unneeded files or folders can be dragged and dropped onto the special bin button to be queued up for deletion later. Disk Falcon even comes with a sci-fi inspired vocal responses to your actions within the program (which, thankfully, can easily be turned off).

Good Idea, something is Broke

I give one start because it fails on all goals except a good interface. You can dress it up any way but still doesn't do a full scan, either crashes about mid 20% on a full hard drive or reports things incorretly

If there were a ZERO rating, this would get it

DON'T BUY!!!! Don't waste your money. I am going to report this to Microsoft as a scanner scam. It has a alluring UI. However, it can't complete a scan of C:\ on a 16Gb Surface RT. Gets to 27% and then restarts. Let run for 15 minutes with no completion, I'm out $3.99, since there wasn't a try. TOTAL FAIL!!!!! I will be tweeting my experience too!

Nice Interface, but terribly slow

Wish I could get a refund. The interface/graphics are amazing, but it takes way too long to scan. On the order of 10 minutes + for a drive with only 7gb of files on it. Other scanning tools can easily do this in 30 seconds or less. If they could update it so that it is fast (probably needs multi-threaded scanning queue), I would be happy. 2012_10_29.

Beautifully Designed

I love how this app looks. I found it fast. Not sure why it is slow for few guys who commented earlier. However I do have problems with the scrollbars on the "Details" and "Volumes" boxes. They get stuck when you move you mouse pointer away.

Incomplete scanning

Never mind that it's woefully slow - this app can't even scan your system disk properly. It won't see your C:\Windows folder, nor your C:\Program Files folder, nor any Hidden and System files - those are going to take up most of the space on your local disk. This is a limitation of the Windows 8 Metro app platform, not specific to this app, but it should be prominently advertised. You'd feel cheated otherwise.

Sorry to also downrate this, but, while you can tell the Developer really did put in an extreme amount of work, it still needs a TON of Metro (or Modern UI for the Nazis) reference design/function language and usage, speed/functionality improvements; practically a re-write of the app. Would buy if you could turn this around 200% and add in Defragment/hard drive tools.

Nice interface, too slow for practical use

The Good Nice interface. I like the different views of the data and the breakdown of file types. Being able to drill down into the folders by clicking on the graph is nice as well. Could potentially be a good view of individual folders or maybe the entire drive on smaller SSD's of Windows RT computers. The Bad I have 120 GB SSD and it was unacceptably slow. Also, if you drill down into the folder while scanning the drive, it loses all progress on the scan. Perf improvements will make this 5stars

Very nice app

Could you please let me know the procedure you access disk info




Platform: PC

Slow but cool concept

It took quite long to analyze the c: drive but, overall, a cool concept vs other programs like WinDirStat. Speed up the disk scan and get more stars...




Platform: PC

Slow app. Practically worthless.

I agree with other reviewers. I think the initial reviews were fakes. This app is really slow. You would want to scan an entire hard drive with it. But, that would probably take a day or more.
