NTFSRatio

NTFS offers file based compression but the compression rate isn't displayed

anywhere. 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. NTFSRatio can be called from the Explorer context menu of any folder.
