I have downloaded to my OpenSUSE box the full install of 3.2 Preview2 for Linux. File is called Alfresco-Labs-3.2_Preview2-Linux-x86-Install. It has no extension. How do I install this thing? Or extract it?
Linux binaries don't normally need an extension - just run it from a shell window. You may need to give it "execute" permissions first. Have a look at "chmod"
