Broken zipped data Import/Export on internal storage on Android 14

[d-faure]

Still in the process to migrate the v3.3.6 (the one available on the play store as a beta tester at this time) from an old Android 8 phone to a newer one on v14.

While accessing the backup/restore section, the application wasn't able to browse the internal storage data (continuous sliding progress bar), whereas a well backups populated Android 8's MyTargets export folder has been transferred on the v14 storage.

I should rely on Gdrive to perform my backup/restore, and thanks to the last PR of @roshanrai06 (lastly made available on the play store as beta) most of the data were migrated.
