I'm trying to figure out how to import a file using the acx command line. If the file doesn't exist I get an expected error of java.nio.file.NoSuchFileException:

When the file exists I get "Unable to copy deleted files."

No matter the processing options I try, macOS, or Windows even the most basic command:

acx import -d master.dsk myfile
Unable to copy deleted files.

If the same file already exists on the disk image, I get: File 'myfile' exists. Which is good.

But why can't I add a new file. What am I not understanding here. I can add files with AppleComnander.jar I just wanted to use this cli tool.
