I have no idea what you mean by this, but why can't you just copy files back and forth using the File class ?

I guess he mean, he has few media files on a pen drive, and he wan't to make a program which does not let those file to be copied to another pen drive. Basically, he wish to stop copying.

Oh - I am usually good at the version of english that happens around here, but I missed that. You can't do it, without writing your own encrypted file system. If you can access the files, you can copy them. No way to stop it.

First of all, you need to choose a file system. See if a file system do have inbuilt switch copying a particular file of not you need to find hooks tho apis which copies any file, but this would be possible if you wanted to stop copying files from a hard drive, not from a pen drive as no OS will allow you to hook to OS.
Another option would be to encode files and somehow, provide a channel to read it.
Another approach could be, creating two partition one visible and second invisible. the visible one will have your executable which will ask for authentication, if authentication passes, make other partition visible else not.

Hope my answer would help you.
