DESCRIPTION:We take the ability to create files and organize them into dir
 ectories for granted. However\, the hard drive certainly doesn't know what
  a file or directory is. It's a job of the file system to bridge the gap b
 etween the user and the "spinning rust"\, the solid-state drive or even th
 e magnetic tape device.\n\nIn this talk\, I'll start by looking at how pop
 ular file systems such as NTFS and ext4 work. Then\, I'll introduce the Co
 py-on-Write concept and show how BTRFS (B-tree file system) employs it to 
 provide a range of new features. The most interesting aspects will be cove
 red in more detail. During the presentation\, the trade-off between space 
 usage and performance of file systems will appear.\n\nFinally\, I'll prese
 nt a working example of BTRFS and some of its distinct features and end th
 e talk by looking at other CoW file systems.
