Java File copy - how to inherit permissions of destination directory

Question

When I copy a file from source folder to destination folder the permissions of the destination folder are not inherited by newly copied file. is there a way in Java where file copy to destination would inherit permissions of destination folder?

Which operating system? What permissions exactly are you referring to? — Duncan Jones, Dec 05 '14 at 08:59
Windows. I am referring to security permissions like which user can access file and how much access control(read/write etc.) one has — Sandy, Dec 05 '14 at 09:04
Such a basic question. I'm looking for a solution as well. :/ — tresf, Aug 20 '22 at 05:34

In java7 - You can do the following

Files.copy(source, target, StandardCopyOption.COPY_ATTRIBUTES)

I have not tested this code. Hope it helps!!

`COPY_ATTRIBUTES` doesn't work on all file systems. On a macOS, it throws `UnsupportedOperationException`. – Abhijit Sarkar Jan 09 '21 at 23:34
Agreed, this is not what's being asked. – tresf Aug 20 '22 at 06:30

Using Files.Copy works fine and I tested this code when renameTo() or FileInput/OutputStream code didn't work.

Try without the StandardCopyOption and the permissions of the destination folder are automatically inherited like this: Files.copy(source.toPath(), destination.toPath());

Hope it can help.
