Create file in netbeans platform

I've made a plugin for NetBeans which parse a Java fil开发者_JS百科e and generate 2 files. I'm writting it to the disk with standard operations (i.e., normal java.io.File). It works, but it takes a while (usually 10 seconds or +) to show on the project (folder) tree.

I was wondering if there is a more efficient way to create this file using the netbeans platform api.

The FileSystem API is the place that you should probably start. You may want to focus on the FileObject and FileUtil classes.
