Yun: compile and verify error message after copying to sketchbook folder

Hey friends,
I was executing the steps in this link:

After I copied the unzipped folder to my Arduino sketchbook folder, open the IDE and upload the YunDiskSpaceExpander sketch, I got error messages per attached file in .txt format. Any advice what is wrong & how to correct this? :slight_smile:


Arduino error msg.txt (12.6 KB)

There is only ONE error in all that mess. Turn off verbose mode if you can't understand everything you are being told.

C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/avr-ar: unable to rename 'C:\Users\user\AppData\Local\Temp\build3d7cca404bc2364684ac76ad0e3dee42.tmp\libraries\Bridge\Bridge.a'; reason: Permission denied

Is there some part of "Permission denied" that is even slightly difficult to understand?
