| Data can be encrypted on the fly using an encrypted sparse disk image. The advantage of sparse images is that the storage initially required by the image file within the host file system is quite low. The image file then automatically expands in chunks, as files are added to the sparse image file system. This means you can set the disk to have 50GB of free space. Yet, initially the image file may only consume 500MB of space within the host file system. | Data can be encrypted on the fly using an encrypted sparse disk image.
