Missing Libraries

So i have been busy more a few months now so have not had much time for tinkering.

Today i came back to the Arduino IDE and tried to compile a sketch, i keep getting an error that the libraries cannot be found. when i follow the directory to the files....they are all present.

My hunch is that this is something to do with them being stored on Onedrive. even so i have no clue how to go about fixing it.

Error below

Arduino: 1.8.5 (Windows 10), Board: "Arduino/Genuino Uno"

readlink C:\Users\seanb\OneDrive\Documents\Arduino\stepper_oneRevolution: The system cannot find the file specified.

Error compiling for board Arduino/Genuino Uno.

this is one of the pre installed libraries

I think you're right about OneDrive. The Windows 10 update caused some breakage. The bug report is here:

The workaround is here:

Brilliant, that worked. Thanks you kindly!
