There is no need to map shares to drives.
First, make sure that you have given read permissions to the file you intend to read. In configuration file 'js-io-rights.conf' (located in <vco-dir>\app-server\server\vmo\conf\ directory), you need to have a line similar to
+r \\192.168.10.120\Shares\test.txt
Then, in your workflow you can use something like
var file = new FileReader("\\\\192.168.10.120\\Shares\\test.txt"); file.open(); var s = file.readAll(); System.log("file content read => " + s); file.close();
Hope this helps.
