Hi pals,

I have downloaded lucene from Index of /pub/lucene/java/4.8.1. I have download both lucene-4.8.1-src.tgz and lucene-4.8.1.tgz. When I extract them, a file named lucene-4.8.1 and lucene-4.8.1-src are created. I am running windows 8 and when I run the files, since they have no extension, I cannot run them! I don't know how I can run them. Please help me with this issue.
