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.
