When I create any web application from netbeans I ger one nbproject folder and jxl file...but don't have any idea about it...what they contain and excluding it we can not open any project...
In the nbproject (short for "NetBeans Project") folder NetBeans saves some configuration-stuff for profiling-settings, build-scripts, etc. So you shouldn't remove it if you want to continue NetBeans as your IDE. (Even though it's good practice to have a build script which is independent from your IDE)
If I delete this folder and again try to open my project...Then my work folder is not consider as a project...
and again I have to create new project to put my code in it...is there any way to create or edit this folder so that there's no need to create new project again??
