How do I generate a .jpk signature file for keystore signing for Android Studio in Windows Command Line?

Question

I am trying to generate a keystore path in Android Studio, how do I find the java.io file? I read and implemented a solution: How can I create a keystore? in the Windows Command Line. I then receive an error after executing the solution. I am running the OS as the administrator.

I have learned that the java.io is generic. I searched my PC for the java.io file and did not find it. I have learned that many of these issues can be avoided by switching to a Linux OS.

The expected result was a.jpk keystore signature file. The actual result is an java.io.FileNotFoundException: my-release-key.keystore (Access is denied) error.

To generate the keystore file from the command line you must run the command line as an administrator. This is achieved by typing cmd in the search bar, then right clicking on the Command Prompt App and then selecting Run as administrator. https://www.howtogeek.com/howto/windows-vista/enable-the-hidden-administrator-account-on-windows-vista/ Follow the directions outlined in How can I create a keystore?
