NTFSRatio
For any folder on an NTFS volume, NTFSRatio shows the size and the compression rate of this folder and also of its subfolders. Compression and decompression can be done inside NTFSRatio with immediate review of the result. Results can be printed or exported.

The disk space tool now also includes the main feature of our discontinued freeware NTFSRatio: TreeSize Free can display the NTFS compression rate.
