Secure Your Files: Create an Encrypted Disk on Which to Store Private Files
The popularity of 'cloud file management' software such as Dropbox and SugarSync has made me re-evaluate my security practices for files on my computers; in the past, I have not put any of my private files (for instance, files with sensitive passwords, or scans of important legal documents) on my shared folders (Dropbox, iDisk, etc.), but I finally came up with an ideal solution to storing and syncing these files. It's like using FileVault, but without the extra overhead of securing every file in your home directory.
