When using the Android Archiver, large files of communication data are generated and temporarily stored on the phone before being archived as per company configuration. Under the Terms of Service specified by Google, TeleMessage is not allowed to delete these files, which can adversely impact storage availability on Android devices.
Several Google Playstore Apps possess an appropriate selective file deletion ability. One such example is the Android AutoDelete utility which provides a solution by deleting files in user-defined folders and subfolders if their last modified timestamp is older than a user-defined threshold.
