Hello new users! The file system visualizer can be found at wheresmydiskspace.com - continue reading to learn more about the development of the tool and the visualization options.
Before buying more storage space it's a good idea to make sure your existing space isn't filled with redundant or old data - or hundreds of downloaded cat videos.
Disk capacity is increasing and while prices continue to drop, those savings are offset by demands for new capacity to store more and larger files. Not only does this mean more primary disk space, but 2x that amount for backups.
Zetta co-founder Lou Montulli may have the answer to this problem. Recently Lou combined his experience with browsers and storage in creating an open-source tool - a File System Visualizer (www.wheresmydiskspace.com) - for analyzing storage usage.
Lou was a founding engineer at Netscape in 1994 when he helped create the first commercial web browser Netscape Navigator. Over the years he's been responsible for the development of many browser related innovations, and co-founded Zetta.net in 2008 - where he continues to serve as VP of Engineering and Chief Scientist.
"The tool was conceived as a method for visualizing multiple aspects of any large file set: an existing file system, a backup or an archive," he says. "This can be a great tool to use if you find yourself running low on disk space and need to find files to delete to free up space."
Or you can:
- Click the link at the top of the page to take you directly to the visualizer.
- There you have three options: you can look at some sample data sets, use a Java applet to collect the data from your local machine and create a manifest file detailing what is in the file system, or you can load a manifest file created in a previous scan.
- If you choose to do a new scan, and there are a large number of folders, the software will prompt you to save the manifest to your disk rather than keeping it in the browser.
We recently had the File System Visualizer tested on a Windows 7 desktop with a third generation Intel Core i7 processor and 16 GB RAM. The scan took approximately 5 minutes. When completed, a message came up that there were 52,993 folders.
The software can analyze a local disk, or an administrator can run it remotely on any mountable drive. At this point it runs on Windows (32-bit and 64-bit) and OSX.
Visualizing Your Data
After running the scan, the software then presents seven different views of the data. The views are illustrated at the top of the page and you can click on any of the images to access that view of the data.
Summary Page - This showed that the test computer had 353.1 GB of data in 52,993 folders containing 364,931 items, with an average file size of 967.7 KB.
Visual Tree - This gives a hierarchical tree visualization of the data. On the left is a pull-down box where you can select to view the data by size, by type or by date. There is also a slider where you can select the tree display depth from one to seven levels.
Screenshot of the Tree View
Viewing by size shows a hierarchical view of the file system and the amount of data in each folder with up to seven levels of depth. To look at just the contents of a single folder, rather than the entire file system at once, just click on the dot next to that folder.
Viewing by type at the first level divided the data into known types and uncategorized. Going to the second depth level divided the uncategorized by their file extension and the categorized into groups such as disk images, games, database, software development, fonts, plugins, office types, settings, executables, media, backup and system. For most of those categories, going to the next level would give the file extensions, but some categories (media, office types and encodings) would further subdivide before getting to their final level.
Viewing by date, the first level divides the data into "1 year and older" and "within 1 year" and shows the GB of data in each category. Taking it to the second level splits the "within 1 year" branch into five levels and the "1 year and older" into each of the years for which you have data. There is no third level available.
Hierarchical List - This view presents the data in list rather than tree format. To get to deeper levels, click the + sign next to any of the categories. In addition to the file names, there are columns for Size in Directory, Total Size and % with children. When you click on the headers for the columns, up and down arrows appear, making it look like the data is sortable by those columns, but it isn't.
Flattened List - This is a sortable, non-hierarchical list of the folders. When viewing by Size, in addition to File Name, there are seven other sortable columns of data in each folder, including Size and Number of Items. The Type and Date views are similarly sortable. In none of these views can you look at a subtree, only at the entire file system. To view a subtree, go to one of the other views and narrow it down to the subtree and view type you want, and then click on the Flattened List visualization.
Your hard drive in "sun burst" view.
Sunburst - A type of pie chart, with rings showing each of the levels of depth. The chart can display each slice as an even size, or can adjust the sizes by the file count or amount of data in the slice. Clicking on any of the slices will move that folder or data point into the center circle, with the rings showing the subfolders or subcategories of that particular subdirectory.
Tree Map - A box type view of the data. As with the Sunburst, the boxes can be sized equally, or sized by data size or number of files. Clicking on any of the boxes will show the details within that subdirectory or data type.
Bubble Chart - This gives two layout options for showing the data: Bubble Chart or Circle Pack. The Bubble Chart shows bubbles for all the items in that category sized by the amount of data in that folder or file type. The Circle Pack presents a hierarchical view of the bubbles. In either view, clicking on a bubble or circle will give the bubbles showing the subcategories of that item.
The File System Visualizer is a quick and easy way to gain understanding of what's on your file system. It's intuitive to use and within minutes, you can start locating what is taking up disk space. Then you can delete or archive anything that is no longer needed, or establish policies to prevent wasted space. Then, if additional storage space is still needed, you can give management a clear visual presentation of how storage is being used in your environment. You can start visualizing your hard drive right now.

Even though it’s now Microservices Journal, long-time fans of SOA World Magazine can take comfort in the fact that the URL – soa.sys-con.com – remains unchanged. And that’s no mistake, as microservices are really nothing more than a new and improved take on the Service-Oriented Architecture (SOA) best practices we struggled to hammer out over the last decade. Skeptics, however, might say that this change is nothing more than an exercise in buzzword-hopping. SOA is passé, and now that people are ...

In the midst of the widespread popularity and adoption of cloud computing, it seems like everything is being offered “as a Service” these days: Infrastructure? Check. Platform? You bet. Software? Absolutely. Toaster? It’s only a matter of time. With service providers positioning vastly differing offerings under a generic “cloud” umbrella, it’s all too easy to get confused about what’s actually being offered. In his session at 16th Cloud Expo, Kevin Hazard, Director of Digital Content for SoftL...

For those of us that have been practicing SOA for over a decade, it's surprising that there's so much interest in microservices. In fairness microservices don't look like the vendor play that was early SOA in the early noughties. But experienced SOA practitioners everywhere will be wondering if microservices is actually a good thing. You see microservices is basically an SOA pattern that inherits all the well-known SOA principles and adds characteristics that address the use of SOA for distribut...

Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does is encourage developers and operations (some might even say DevOps) to re-evaluate scaling strategies. In particular, the notion is forwarded that an application should be built to scale and then infrastructure sho...

Microservices are the result of decomposing applications. That may sound a lot like SOA, but SOA was based on an object-oriented (noun) premise; that is, services were built around an object - like a customer - with all the necessary operations (functions) that go along with it. SOA was also founded on a variety of standards (most of them coming out of OASIS) like SOAP, WSDL, XML and UDDI. Microservices have no standards (at least none deriving from a standards body or organization) and can be b...

Our guest on the podcast this week is Jason Bloomberg, President at Intellyx. When we build services we want them to be lightweight, stateless and scalable while doing one thing really well. In today's cloud world, we're revisiting what to takes to make a good service in the first place. Listen in to learn why following "the book" doesn't necessarily mean that you're solving key business problems.

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Microservices, for the uninitiated, are essentially the decomposition of applications into multiple services. This decomposition is often based on functional lines, with related functions being grouped together into a service. While this may sound a like SOA, it really isn't, especially given that SOA was an object-centered methodology that focused on creating services around "nouns" like customer and product. Microservices, while certainly capable of being noun-based, are just as likely to be v...
