Hovic:
Where is the SketchRoot?
can you give a screen shot what you mean?
It is the folder name on your PC of where ever your sketches are saved to when you quit the IDE. The full path name is shown in the arduino IDE under files/Preferences, in the top window named Sketchbook location. My path sketch folder is named C:\Documents and Settings\Primary Windows User\My Documents\Arduino when using arduino version 22 and it's path sketch folder name is C:\Documents and Settings\Primary Windows User\My Documents\Arduino\Arduino1 when I'm using arduino version 1.0.3.
This is the folder name where you can create a folder named libraries where you can then install 3rd party library files and example sketches for the library. The arduino core also has a folder named libraries that it populates with the 'official' arduino library files that come with IDE installation distrubution. You should not add or erase files in that folder, just your arduino users sketchbook folder/libraries folder.
