Portable Folder Size

Portable Folder Size is a simple-to-use program with a pretty self-explanatory title - it allows you to calculate the size of the folders stored on your computer.

Since installation is not necessary, you can store Portable Folder Size on a removable device (such as a USB flash drive), plug it into any computer and directly run the executable file. But the important part is that your Windows registry keys will remain unchanged.

The interface of the software is based on a standard window in which you can select the drive or folder via the file browser only, since the "drag and drop" method is not supported.

You can easily calculate its size by pressing a single button. Once the analysis is complete, you can check out the size, along with number of files and folders included in that particular location.

You can check out a treeview and key code (folders are color-coded, depending on their size), as well as a graphical comparison of folder sizes. In the "Options" area you can enable Portable Folder Size to show the folder size on the left or right, as well as set up the size limit for each key in the key code.

Portable Folder Size runs on a very small amount of system resources (which is barely noticeable) and has an excellent response time. We haven't come across any issues during our tests, since Portable Folder Size did not freeze or crash. Putting aside the simplistic interface, we strongly recommend this tool to all users.
