To find the location of your_sketchbook_folder, go to top menu in Arduino IDE:
Windows: File → Preferences
Mac OS: Arduino Preferences

The structure of your your_sketchbook_folder should now look like this, along with your other sketches (if you have them):

your_sketchbook_folder/libraries/Blynk
your_sketchbook_folder/libraries/BlynkESP8266_Lib
...
your_sketchbook_folder/tools/BlynkUpdater
your_sketchbook_folder/tools/BlynkUsbScript
...

☝️ Note that 

  • libraries should go to libraries 
  • tools should go to tools
