APK Extractor & App Backup

• Extract APK files from user apps and system apps
• Batch backup many apps at once, without root access
• Pick a custom export folder on internal or external storage

• What can this app do?
• Where are extracted files saved, and can I change it?
• Why is an app exported as XAPK instead of APK?
• Can I customise the exported file name?
• Why are some apps missing from the list?
