What is an ABU1 file?
An ABU1 file is a backup file created by ASUS Backup, an Android app used to backup and restore data on ASUS ZenFone devices. It contains a backup of data from the ZenFone device, such as contacts, SMS messages, call logs, pictures, videos, music files, documents, personal settings, apps, and app data.
ASUS Backup can be used to backup data stored only in external storage. Any data stored in internal storage must be copied and moved manually by the user to external storage in order to be backed up.
When you create a backup of data on your ZenFone device, one or more ABU1 files are created and stored in the "ASUSBackup" folder on the SD card of the device. ABU1 files can be opened by ASUS Backup to restore the data to the ZenFone device.
NOTE: ASUS Backup has been discontinued.
