I have some files that I occasionally send to my family members. The thing is, because they contain sensitive information (finance records, sometimes they're family videos), I don't like just uploading it to my iDisk. What I've been doing is going into Disk Utility, creating a password-protected disk image, then zipping up that file. It's a few layers of security, and the 128-bit encryption seems good. The thing is, I'm not sure what settings to use. Here's a screenshot of the window that comes up when creating a new disk image. What options should I choose from here? I can do a Get Info on all of the files I'm putting in the disk image, but it would be easier to have it auto-fit whatever I put in, eliminating any unused space. I'm not sure of what to put for Format, Partitions, and Image Format, and I'm surprised that I have to choose a size since I've heard there's a way to have it automatically fit the files. Is there a way to select my files/folders in the Finder and have a disk image created from the selection? Thanks for your help!
