HarmonyOS 可以获取到storage->cloud->100->files->Download目录下的文件吗

该目录的沙箱路径是：file://docs/storage/Users/currentUser/Download/

可以参考以下示例获取文件沙箱路径:

import picker from '@ohos.file.picker';
let DocumentSelectOptions = new picker.DocumentSelectOptions();
let documentPicker = new picker.DocumentViewPicker();
documentPicker.select(DocumentSelectOptions).then((DocumentSelectResult) => {
  console.log('DocumentViewPicker.select successfully, DocumentSelectResult uri:' + DocumentSelectResult);
}).catch((err) => {
  console.error('DocumentViewPicker.select failed with err: ' + err);
});
} catch (err) {
  console.error('DocumentViewPicker failed with err: ' + err);
}
