How can Copy and move `assets` folder data in runtime?

I have created 2 directories in the assets folder.
One is android and second is window.
--assets
1:- android
2:- window
I have a few files inside in the android folder. I need to copy all of them from the android folder to the window folder at runtime. How do I do it?

You can't. The assets folder is read-only and cannot be modified after compilation.
You can copy your files into a similar structure on the internal storage if you wish to do so.

Not sure I get your question fully right as explanation is bit messy, but while APK is ZIP file, you should really consider it read-only. So you can copy files out of it but you cannot add anything to your APK nor alter it at runtime.

How to put extra files in Android APK with Eclipse?

I want to add a text file to my APK root. This file will not be used in the application but it will stay there for manual extraction of the APK.
I tried to put it into the root of the project in Eclipse but it didn't include that file in the APK. I don't want to put it into assets folder. Can't I put it to the root?

Use the assets folder.
According to Android developer
assets/
This is empty. You can use it to store raw asset files. Files that you save here are compiled into an .apk file as-is, and the original filename is preserved. You can navigate this directory in the same way as a typical file system using URIs and read files as a stream of bytes using the AssetManager. For example, this is a good location for textures and game data.

Files that are not put into any of the main directories of your android project will NOT be included in your apk. You MUST put the file in the assets so it can be accessed within the application as an external resource/file.

Can anybody help me with this?

There is no "path of the assets directory" on the device.

No, because there is no "path of the assets directory" on the device. Please use AssetManager to retrieve an InputStream to your assets as needed.
Since android has a file size restriction on files inside raw directory, I will be placing my files in assets directory, and during runtime, I would be retrieving them as need
The "restriction" is the same for assets, AFAIK. The usual way to circumvent the "restriction" is to give the file an extension that Android's build tools will not try to compress (.mp3 works IIRC).

Try using
AssetFileDescriptor
