No such file or directory

No such file or directory

I lack understanding of how the Library functionality works.

Trying to compile a sketch, but I meet the error No such file or directory at #include <BlynkApiArduino.h>

In my Sketch Location folder:
C: \ Users \ Sune_Bielefeldt \ Documents \ Arduino
here i placed the Standard Blynk libraries to be used for this sketch, and as seen from my screenshot there is the current file> BlynkApiArduino.h> also in the folder.

Still, I receive the message No such file or directory, why …

You must install libraries to the libraries subfolder of your sketchbook folder. You can find the location of the sketchbook folder in the Arduino IDE at File > Preferences > Sketchbook location.
