Why does arduino create a readme file in a libraries subfolder under the libraries folder? Whenever I launch the arduino IDE the message appears indicating an invalid library. I have deleted the subfolder but it still is created. What to do?

What does the "readme" file say?

Hint: The readme.txt file isn't what causes the invalid library message.
You've got another issue.

Quite right. I just created a subfolder in "libraries", placed a "readme.txt" file inside it, and the IDE opened without a hitch.
@Guy_Gadois , could you please post your full error message. (And post it between code tags please.)
I don't know what "code tags" means. The readme text file reads: "For information on installing libraries, see: http://www.arduino.cc/en/Guide/Libraries". I have installed the arduino libraries to "C:\arduino\libraries". Is this not the correct place? If not, where should it be installed?
Thanks for the help.

Your main Arduino "libraries" folder will be in your installation directory. In my case, that's "C:\Program Files\Arduino\libraries". It contains the libraries that are automatically installed with the IDE.
Additionally, you should have a second "libraries" folder for 3rd-party libraries that you install yourself. It should be located in your "Sketchbook" folder.
The "Sketchbook" folder path will be listed in >File >Preferences under "Sketchbook Location". You can use the default "Sketchbook" location, or create your own and put it's path here.
If you post your error message, we can possibly help further with regard to the "invalid library" that you mention.
Does it stop you from using Arduino altogether?
I can't upload the sketches because windows has installed a driver and now there are no ports showing in the device manager. It is now an "unknown device". Before this happened, I could upload sketches even the invalid library messages were displayed. I have posted the port problem on this forum as well.
Attached is a jpg file of the messages.
Thank you for your help.

Hmm. It doesn't give a lot of info, especially it doesn't say exactly which library might be the problem.
I see that you have a "libraries" folder inside another folder called "libraries", but that's not the cause of the problem.
(I just re-created that situation and everything works fine.)
I saw your other post, but couldn't think of an answer, so didn't reply. It's the more important problem right now, so ignore this for the moment and concentrate on that one. Then when that's solved we can worry about this.
The warning is:
Invalid library found in C:\Arduino\libraries\libraries
I guess you have set your File > Preferences > Sketchbook location: to C:\Arduino\libraries. That is not a valid location for your Sketchbook for a couple reasons. It causes this warning and your sketchbook will be deleted whenever you upgrade the Arduino IDE. Please choose a different location for your Sketchbook, move any files that you have saved to the new location, and delete the C:\Arduino\libraries\libraries folder.
