Saving files to SD Card - Ionic v1

Hi, I’m working on an app based in Ionic v1 and I need to save some files to the device SD card. To complete the download it uses the $cordovaFileTransfer plugin passing the path with cordova.file.externalDataDirectory, but it is returning the app directory in the internal storage.

So, somebody knows if it’s possible to access/write files in SD card storage using Ionic v1?

Thanks a lot.
