URL Schemes

local://$USERCONTENT/ — User content directory for persistent file storage.

var path = Host.Url("local://$USERCONTENT/folder/file.txt");
path.ascend();                  // -> $USERCONTENT/folder/
path.descend("file.txt");       // -> $USERCONTENT/folder/file.txt

package://PackageID/ — Package resources directory (PackageID from metainfo.xml).

var res = Host.Url("package://" + packageID + "/resources/menu.xml");

memory:// — Temporary in-memory URL. Supports ascend()/descend() navigation and Host.IO.findFiles().

var mem = Host.Url("memory://MyNamespace/", true);
mem.descend("child");   // url -> "memory://MyNamespace/child"
mem.ascend();           // url -> "memory://MyNamespace/"

Document Path Access

The active document's .path property returns a Host.Url-like object.

function getSongFolder(fileName) {
  var docManager = Host.Objects.getObjectByUrl("://hostapp/DocumentManager");
  var doc  = docManager.activeDocument;
  var path = doc.path;
  path.ascend();
  path.descend(fileName);
  return path;
}
