My bootcamp partition is 65GB and is currently using 49GB of the 65GB. I just created an image on an external drive in preparation for replacing the SSD in my rMBP. The image is ~24GB. Is this typical? Does Winclone compress the bootcamp files when creating the image?
Winclone doesn’t copy the swap files or hibernate files, which can be large, and also compresses the data. If you have 16GB of memory, the hibernate / swap could account for a lot of that space.
