[[Image:directory-structure-1.png|thumb|right|350px|In Unix / Linux (as opposed to MS Windows), there are no drive letters (such as '''C:''', or '''D:''').<br><br> All files and directories appear under a single ancestor directory called "the '''root''' directory".<br><br>A path points to a file system location by '''following the directory tree hierarchy''' expressed in a string of characters in which path components, separated by a delimiting character, represent each directory. The '''delimiting character''' is most commonly the slash ("'''/'''").]]

To better '''organize''' files (eg. text, images, documents, spreadsheets, programs) within your Matrix account, they should be stored in '''directories'''. To further organize <u>many</u> files, directories may contain sub-directories.

The Unix/Linux file system is '''hierarchical''', similar to other operating systems such as '''Windows''', '''Mac OSX''', etc.
