2.6) User Interface: Current Folder

The Current Folder pane shows the contents of the directory ('folder') you are currently in - i.e. the default filespace with which Matlab will exchange inputs and outputs.
By default when you begin a session, the current directory is either your personal workspace (Windows) or the directory from which Matlab was started (Unix/Linux).
You can navigate around your computer's filing system within the Current Folder pane, moving into a directory by double-clicking on the corresponding folder icon.
The contents of directories can be viewed by clicking the plus sign next to the corresponding folder icon.

It is useful to have all of your Matlab files (scripts, data files, etc) in one place. Consider creating a work directory within your home directory that is dedicated to your Matlab work.
It is best to have a separate directory for each Matlab project you are working on.
If you have a large number of data files, consider placing them into their own subdirectory.
An organized directory structure makes it easier to back up and find your files.
