My TreeSize trial period has expired.

I tried both TreeSizeFree and Folder Size but they require a licence to open UNC dir paths.

Therefore I'm now looking for an opensource TreeSize equivalent to compare directory sizes.

Is there any?

  • Does JDiskReport work for you?

WinDirStat is a very commonly used open source Windows app for graphical directory size comparison.
