How to access mapped network drive from java application?

I have a network drive mapped as:

net use h: \ip\servername

I have a normal java application that is going to read a txt file from that drive.

Code:

File file = new File("H:\\MyFile.txt");

try {
    byte[] bytes = Files.readAllBytes(Paths.get(file.getAbsolutePath()));
} catch (IOException ex) {
    Logger.getLogger(JavaApplication25.class.getName()).log(Level.SEVERE, null, ex);
}

When i run this program from my computer (windows 7 or from another computer with windows vista), the program runs without any problem.

However, when i run this program from a computer with Windows 10, i get the following error:

java.nio.file.NoSuchFileException: H:\MyFile.txt

But if i run the application using the following code it works:

File file = new File("\\ip\servername\MyFile.txt");

try {
    byte[] bytes = Files.readAllBytes(Paths.get(file.getAbsolutePath()));
} catch (IOException ex) {
    Logger.getLogger(JavaApplication25.class.getName()).log(Level.SEVERE, null, ex);
}

How can i use the mapped drive letter instead of using the full address?

Got same issue. Resolved by editing windows registry

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"EnableLinkedConnections"=dword:00000001

If it works, it means your IT dept. should manage better network policies.
