title: Remove unused source code files using eclipse/ Flash builder 4.6
body: <p>i have a project having lots of file, around 4500 file in all Project. i separated it in 40 library project.Now my problem is that it taking too much time to Compile. so i increase a memory of Flash builder. This gives me little improvement to compile. i am sure that i have too much file which is not used in my project. so now i want to remove it by plug of Flash Builder / Eclipse. Because it is too much headache process to see that "xyz.as/mxml" file is used in any other file or if it is used in Other file say "abx.as/mxml" then again i have a question that "abx.as/mxml" is useful file or used in any other file. so you have any idea or hint please give me. Thanks in advance...</p>
