The documented difference
Google documents Safe folder as a place to hide files and control access with a PIN or pattern. Its help page says direct Share and Back up to Google Drive actions are unavailable inside Safe folder. See Files by Google Safe folder’s official documentation.
Side-by-side decisions
| Question | NullVault | Files by Google Safe folder |
|---|---|---|
| Ordinary access | Different patterns address separate spaces | PIN or pattern access to Safe folder |
| Backup decision | Platform-specific encrypted-backup workflow | Do not assume a direct Google Drive backup action is available inside Safe folder |
| Archive types | Photos, videos, files and notes managed in the app | Files handled through Files by Google |
When Files by Google Safe folder is the better choice
Safe folder may be the better fit for a simple private-file area when you already use Files by Google and do not need independent pattern-addressed spaces. Familiar file management can be more convenient than adopting a separate archive.
When NullVault fits
NullVault is worth evaluating when you need its explicit backup and recovery workflow or separate local vaults. Either choice requires planning for device loss; a lock screen alone does not make a file recoverable. Read NullVault’s features and security limitations for the released scope.
Before you move an archive
Follow Google’s instructions before moving files out of Safe folder. Confirm the exported copy, import a non-sensitive sample into NullVault, and test recovery before removing the original. Never reset a folder merely to test what happens to important files.
