Pro-tip:
Save all your personal files to a separate external drive (USB thumb drive) formatted as NTFS. They're cheap, so get two or three and sync them for backup purposes using rsync and Grsync (the rsync GUI).
If some catastrophic event occurs where you have to bail quickly, you can grab that drive and run, and you'll still have all your important files which can be read by Mac, Windows or Linux.
If your Linux (or your Windows) crashes, you've still got those files.
Never mix your files and OS files. I've gone so far as to bind-mount the built-in Documents / Music / Pictures / Videos local directories so they're all on external drives.
