Q:

Flex 3: How Can I Work on a Copy of a Project?

I've got a Flex 3 project. It works fine. But, I'd like to make some major changes to it.
Is there a way to duplicate the project and work on the copy? It's critical that I don't screw-up the original. But, I'd like to make major changes to the copy. 
I tried making a copy of the project and renaming it. But, when I try to import the copy into Flex Builder, it says: "A project with the same name already exists in your workspace. Rename or delete the existing project." -- even though I renamed the project file and the main mxml file. 
Unfortunately, I don't have a subversion program set-up, and I think that it will be a hassle to do so. Is there an easy way to work on a copy of a project?
My project uses a mySQL database. I don't know if that makes any difference. 
Thank you.

A:

First thing first. You need to have a version management, if you are doing branching and merging. Creating local subversion repo is not that big a deal, but I use local git repository and it takes a minute to initialize a repository.(local)
Now on to your question. You can create a copy of your project and the reason why your IDE is complaining is you have copied  the project folders also ( project folders like .classpath and .project generated by your IDE). To make a copy, create a new project in your IDE and just copy the src folder ( and other versioned files  ). You should be fine then.
