createDirectory(....)

[Amn]

"*/Files.createDirectory(dir_path)/*" gives an error, such as, 
"*/java.nio.file.NoSuchFileException/*" when I tried to create a 
directory outside the NB15 project directory, i.e. 
"//home/my_home/App_Home_Dir/Sub_App_Dir/db/DatabaseTest.db/". However, 
when the dir_path is just the file name (/DatabaseTest.db/), NB15 has 
not problems creating it in the project's home directory. I don't need 
the new file in the project's home directory, I need it in the 
"/home/my_home/App_Home_Dir/Sub_App_Dir/db". This might just be a matter 
of setting a switch in NB15, which is what I am hoping for. So, any help 
would be much appreciated.

By the way, I am using a Debian 11 box.

Thanks in advance.
