Folder Space

Folder Space is a lightweight and portable application that calculates the size of directories to find out the largest items taking up the most space on your hard disk.

Scan directories to identify the largest folders

It can help you identify ways of freeing up space by removing unnecessary data. The tool features an option for exporting information to file for closer inspection and safekeeping.
As far as interface is concerned, Folder Space opts for a standard window with a simple design and neatly structured layout, where you can get started by selecting a folder to scan.

Export search results to file

Once the operation is over, you can check out the full path and size of each directory, as well as sort the items by any of these criteria. The status bar reveals the total size. Meanwhile, the entire list can be saved as a plain text document by indicating the destination directory and file name.
It's automatically opened in your default word processor afterward. Apart from the fact that you can cancel an ongoing scanning operation if it takes too long or if you simply change your mind, there are no other noteworthy features provided by this piece of kit.

Portability benefits

Since there is no installation involved, you can copy the downloaded files to a preferred directory on the disk or to a removable storage unit, in order to seamlessly launch the utility on any PC without setup. It doesn't change system registry settings and includes the source files in the downloaded package.

Evaluation and conclusion

We haven't experienced any stability issues in our tests, thanks to the fact that the software utility didn't hang, crash or indicate errors. System resources consumption was minimal, since it needed a low amount of CPU and RAM to work properly.
Thanks to its approachable interface and options, Folder Space delivers a straightforward solution for scanning directories to discover the largest ones and take the necessary measure required for organizing disk space.
