Could you please describe step by step how to reproduce it? It's not clear for me and what I have tried it works.

1. Close IDE
2. Add some new files via a file manager
3. Start IDE
4. After scanning sources, new files were not copied to another location (both locations are on the same machine w7 disks c and d)
5. modify one of the new files, save, copy to another location works only for edited files. Other new files were not copied
6. If you add a new file and IDE is running, everything works as expected

I'm sorry, but I need to clarify more things. What exactly do you mean by copying to another location? You mean to the something like when you run a project and the sources are copied to the destination folder?

Click on project properties -> sources. There is checkbox "copy files from sources folder to another location". There I have specified my another folder.

Usualy, files are copied after saving them. And I think, thats a problem. Copy support should work also after initial or manually rescanning sources, not only on save event.

Thanks for clarification. Now it's clear.

The current copy support is based on the file events. So copy support doesn't know nothing about files that are created, when the ide doesn't run. The current implementation copies files directly (without an event) only when the option "Copy files from Source folder to another location"  is set to true. But there is a condition that the target folder has to be empty.

I would create very simple fix, that will copy all files during startup, but we probably don't want to do it. The reason is slowdown during the IDE startup / opening a project. It requires at least two more disk touches that can significantly increase the time, when a project is bigger (has many source files).

So probably the best solution would be to create a new action in context menu over the Source node (the name can be "Copy into ${location}") that will enabled only when the option "Copy files from Source folder to another location" is turned on.

The workaround is to copy such files (created when the ide was down) in to the target folder manually. 

There is one more bug, when you switch "Copy files from Source folder to another location" off, then you are not able to switch it on again for the same folder through ui. Workaround for this is go to the nbproject/private/private.properties file and set option "copy.src.files=true";

I can reproduce it.

Project area. Reassigning.

This scenario is not supported, sorry.
