The reason I recommend using the 'sparse disk image' now becomes clear. I set the disk image to be 10 GB, but it's not even 50 MB on my drive. This is because the Sparse Disk Image format grows in size only if needed and will top out at the preset 10 GB, so it will use a fraction of the size you set at first and it may take you years to get to the preset size. If you find you need a bigger disk image down the road, just create a new one and copy the data over.If you want to encrypt an already existing folder, go back to step 2 and select 'Image From Folder.'

Otherwise, move to step 6. • Select the folder you want to encrypt, set a name, encryption strength and image format (read/write if you want to make changes to the contents later on). Keep in mind that the created disk image will not be able to store more files than what's already there. This makes the 'Image From Folder' method a good one for long term storage of files you're done with. If you need to frequently access the contents or add to it, a sparse disk image is a better way to go. Encrypt Documents and Files Data has to leave your Mac, and for any number of reasons. It's safe on your Mac, but what if you need to email or message a document or file to someone? There are several ways to password protect your documents and files, most of them with the same end result.

I think having a copy in encrypted zip format (for Windows, and probably many other OSes), and another copy in encrypted Mac disk image format for OS X? This'll be a little annoying to set up (or update), since you need to create/update two copies in sync. How to create the disk image depends on whether you expect to need to update the data. If it will be updated, run Disk Utility, choose File > New > Blank Disk Image, then set the volume name to something reasonable, set the size larger than you expect to need, select an encryption mode, and set the Image Format to 'sparse disk image'.

Once set, when you start your Mac from your normal startup disk, you see the normal login window where you enter your user account password. If you try to start up from another drive, or from OS X Recovery, your Mac pauses startup and displays a lock icon with a password field instead.
