# Add & open files

**What you'll do:** Put files into your Drive (or a vault) and open them again — all encrypted, all in the tools you already use.

**Why it matters:** Everything you add is encrypted on your device before it's written or synced. Opening decrypts on-demand, in memory only.

### On macOS (Finder) <a href="#on-macos-finder" id="on-macos-finder"></a>

**Add**

1. Open Oten Drive and unlock your Drive or vault.
2. In **Finder**, drag files or folders into the Oten Drive location (or copy-paste). Any file type works.
3. The app encrypts each item and syncs the encrypted blob when sync is enabled.

**Open**

* **Double-click** a file in Drive to open it directly in Finder; double-click a vault record to open it as expected. The file is decrypted on-demand and opens in its default app.
* Right-click for the context menu to **Lock vault**, **Share**, and other actions without opening the main app.

### On iOS (Files app) <a href="#on-ios-files-app" id="on-ios-files-app"></a>

1. Unlock the vault in the Oten Drive app so it mounts as a location in **Files**.
2. In **Files**, browse into Oten Drive to view, create, rename, copy/move, compress, and preview supported file types — every operation runs through the encryption layer.

### Good to know <a href="#good-to-know" id="good-to-know"></a>

* **Large libraries:** the Drive view uses **Load more** pagination so accounts with many files stay fast.
* **Search:** find files and folders by name within a vault.
* **Integrity:** writes are protected against corruption, and files stay sealed even if the app crashes.

**Common mistakes**

* **Editing outside the mounted location and expecting encryption.** Only files placed inside the Oten Drive Drive/vault are encrypted and synced.
* **Turning off sync and expecting other devices to update.** Rotation and multi-device updates need sync enabled.
