Sketch problem

Dear all,

I am trying to download a sketch, i.e. for example MainSketch27Jan.tar.gz How do I install and open them in Arduino pls?

Thx

You need to un-gzip and un-tar the file, before it can be opened by the IDE.

Mac and Linux have support built in, not sure about Windows.

Someone recommended 7zip: http://www.7-zip.org/ If you have tar it will do the job (checkout the z option)

You must untar it.
I do not know what OS you are using.
If you are using linux, see here: http://www.tech-recipes.com/rx/138/extract-a-gzip-compressed-tar-archive-in-linux/
If you are using windows, the free trial of winrar works.
