I use Win10 . I have in " Contribited libraries " a file ( MCUFRIEND_kbv ) which I like to remove from the library . I tried C:users AppData.... libraries , C:users, documents , arduino....libraries and even C:programfiles(x86) , Arduino, libraries .... but was unable to locate this file . A search on my computer didn't found this file or locate the file but she is still there because when I try to open a new MCUFRIEND_kbv2.9.8 , Arduino refuse because the file is already existing. Do someone have any idea where this file can be hidden?
File > Examples > MCUFRIEND_kbv > click on any of the library's examples
Sketch > Show Sketch Folder
That will only work if the library has an example sketch. In case it doesn't, you can find the location by doing this:
File > Preferences > Show verbose output during: > compilation (check) > OK
File > New
Sketch > Include Library > MCUFRIEND_kbv
Sketch > Verify/Compile
After the compilation finishes, examine the contents of the black console window at the bottom of the Arduino IDE window. You will need to scroll up to see it all. Somewhere in that output you will find the path to the library. You can find it more easily by selecting the contents of the console, copying and pasting it to a text editor (you can use the Arduino IDE if you like), then searching the text for MCUFRIEND_kbv.
