i understand this function listen to the PHYSICAL files and directory
changes (renaming , deleting , adding a new File) and notify to the
implementation of FileChangeListener to execute the corresponding code ,
but it doesn't work for me

1. The above should work on individual files, but if you wish to use one listener to check for changes anywhere beneath a file tree, you will need
addRecursiveFileChangeListener in 6.8.
2. You will not be notified if changes on disk (using java.io.File methods, or out-of-process changes) unless there is some trigger causing NetBeans to look for them. See
#26230 for a request for native-backed polling.
Anyway I wonder what it is you're trying to accomplish. If you have a physical file tree, you can treat it as a FileObject tree just using FileUtil.toFileObject. If you
want to treat it as read-only but have memory-backed changes as an overlay, use MultiFileSystem with FileUtil.createMemoryFileSystem. |
