Bootcamp image size

Just did my first Winclone backup of bootcamp partition. Everything worked.

Then I found the newly created image file was significantly smaller than the used size in bootcamp partition. Like Finder reports 175GB used in Bootcamp partition while the newly created Winclone image file was only 19GB.

Is this normal?

Sometimes the finder does not show the correct size. Try control clicking on the image, and select Show Package contents, and then look at the size of the Windows.wim or boot.img.gz.
