How do I remove a library from the arduino environment

Question

In the Arduino GUI on windows  if I click on Sketch --  Import Library  at the bottom of the menu there is a section called  Contributed    Unfortunately  I had misclicked and added a library I did not want to that list   How can I remove it from that list   The help page only mentions that  If a sketch no longer needs a library  simply delete its  include statements from the top of your code  but it does not mention how to remove the library from the list of contributed libraries

In Elegoo Super Starter Kit  Part 2  Lesson 2 12  IR Receiver Module  I hit the problem that the lesson s IRremote library has a hard conflict with the built-in Arduino RobotIRremote library   I am using the Win10 IDE App  and it was non-trivial to  quot move the RobotIRremote quot  folder like the pre-Win10 instructions said   The built-in Libraries are saved at a path like  C  Program Files WindowsApps ArduinoLLC ArduinoIDE 1 8 42 0 x86  mdqgnx93n4wtt libraries You won t be able to see WindowsApps unless you show hidden files  and you can t do anything in that folder structure until you are the owner   Carefully follow these directions to make that happen   https   www youtube com watch v PmrOzBDZTzw After hours of frustration  the process above finally resulted in success for me   Elegoo gets an F  for modern instructions on this lesson

The answer is only valid if you have not changed the  Sketchbook Location  field in Preferences  So  first  you need to open the Arduino IDE and go to the menu   File - gt  Preferences    In the dialog  look at the field  Sketchbook Location  and open the corresponding folder  The  libraries  folder in inside

I had to look for them in C  Users Dell AppData Local Arduino15   I had to take help from the  date created  and  date modified  attributes to identify which libraries to delete    But the names still show in the IDE    But it is something I can live with for now

For others who are looking to remove a built-in library  the route is to get into PackageContents - gt  Java - gt  libraries  BUT   IT MAKES NO SENSE TO ELIMINATE LIBRARIES inside the app  they don t take space  don t have any influence on performance  and if you don t know what you are doing  you can harm the program  I did it because Arduino told me about libraries to update  showing then a board I don t have  and when saying ok it wanted to install a lot of new dependencies - I just felt forced to something I don t want  so I deinstalled that board

Go to your Arduino documents directory  inside you will find a directory named  Libraries   The imported library directory will be there  Just delete it and restart the Arduino app   Your Arduino library folder should look like this  on Windows      My Documents Arduino libraries ArduinoParty ArduinoParty cpp   My Documents Arduino libraries ArduinoParty ArduinoParty h   My Documents Arduino libraries ArduinoParty examples          or like this  on Mac and Linux      Documents Arduino libraries ArduinoParty ArduinoParty cpp   Documents Arduino libraries ArduinoParty ArduinoParty h   Documents Arduino libraries ArduinoParty examples   The only issue with unused libraries is the trivial amount of disk space they use  They aren t loaded automatically so don t take up any application memory of the Arduino IDE

Quote from official documentation as of August 2013      User-created libraries as of version 0017 go in a subdirectory of your default sketch directory  For example  on OSX  the new directory would be   Documents Arduino libraries   On Windows  it would be My Documents Arduino libraries   To add your own library  create a new directory in the libraries directory with the name of your library  The folder should contain a C or C   file with your code and a header file with your function and variable declarations  It will then appear in the Sketch   Import Library menu in the Arduino IDE    To remove a library  stop the Arduino IDE and remove the library directory from the aforementioned location
