5 Free Portable Folder Analysis Tools for Windows

As time goes and files piled on your computer, you will eventually run out of disk space. And when it happens, it would be a lot helpful having a nice tool handy that helps you to analyze your disks and folders to find out what’s been filling up space.

And Here are 5 of these tools that do this kind of job well, efficient, free of charge, and portable.

SpaceSniffer

SpaceSniffer 1.2.0.2

SpaceSniffer is a freeware disk space analyzer for Windows that make use of the Treemap concept to view the current disk usage to immediately provide the perception of where big folders and files are placed on your devices.

It’s a very simple and easy-to-use tool that serves the purpose without a lot of other features. It works on localexternalnetwork drives, as well as any folders that you can get access to on your computer.

WizTree

WizTree works pretty much the same way as the other tools listed in this post. It only works on local NTFS drives and lists the scanning results in a tree-view layout with a feature that lists the top 1000 largest files scanned.

What makes WizTree standout among other tools is its speed. It works very fast, arguably the fastest one on the planet. If you only need to work on your local disks, this could be the one to go.

TreeSize Free

TreeSize Free is the one I use the most at work. It scans local disks and folders, including the synced cloud shares. It also works on the network drives that are not within a Windows domain, which requires a professional version. Comparing to WizFree, it’s relatively slow but equips with more features and displays more info.

With installed version, instead of portable one, you can have a real-time folder monitoring feature and launch the tool from the context menu of any folder or drive.

GetFolderSize

GetFoldersize 2.5.24 (Portable Edition) - 2015-01-30 13_30_14

GetFoldersize allows you to determine the size of folders and sub-folders on your hard drive. Determine which programs are taking up your hard disk space. For each folder, you can display the total file size and the number of files and subfolders in the folder.

Xinorbis

Xinorbis __ 6.2.1 _ January 20th 2015 - 2015-01-30 13_36_58

Xinorbis is one of the oldest but mature disk analyzer tool that uses tree display, graphs, and tables in order to reveal the content of files. It’s simple but is packed with a long list of features to provide you a sophisticated mix of graphs, tables and tree displays to give a complete overview of the contents of any hard disk, folder, removable or network drive.

It also supports a seamless integration with SQlite3 or ODBC for its folder history data archive so you can compare the contents of a hard drive or folders at any time or date down the road.

Which one to choose?

Essentially, all 5 tools listed in the post work quite well in analyzing folder structure on a Windows system. Specifically, if you like a more visualized tool you may like SpaceSniffer better. If you like a speedy one, WizTree is the one to go. But if you are the one always wanting to have one packed with a lot of features, you should head over to TreeSize and Xinorbis.
