How to move files using app.system()?

[Whatevermajorloser]

I am trying to move a file from a location to, say, my desktop. How do I do this using app.system()?

I found this thread How do I move files through Extendscript? which has started me on the right path, but I don't know AppleScript. I did a bit of searching and put this together, which appears to do nothing (ExtendScript just says Result: 256):

app.system("osascript -e 'tell application \"finder\" move POSIX file \"/path/to/file.tif\" to POSIX file \"~/Desktop\" with replacing'");

What am I doing wrong here?

I see. Yeah using getFiles on a network drive is not a good idea.

It is a shame that you can't retrieve the result from an app.system
