Everyday use

Unlock and open

  1. Plug in your NOOKK Key — unlocking starts automatically by default. If you've turned that off, click the lock icon → Unlock NOOKK Drive
  2. Enter your key's PIN (if you set one), and touch the key when it blinks
  3. Once the status shows Unlocked, the "NOOKK" drive appears in File ExplorerFinder

Click the lock icon → Open NOOKK Drive to open it directly. Use it like any USB drive — everything you put in is encrypted automatically.

If you plug in the key while your computer is still on the sign-in screen, NOOKK waits until you reach the desktop before asking for your PIN.

Lock

Your NOOKK Drive locks immediately and disappears from your computer when any of these happens:

Remove your NOOKK KeyThe most common way — it locks the moment you unplug it
Lock NOOKK DriveChoose it from the lock icon menu to lock without removing the key
Emergency lock shortcut Ctrl Alt Shift L Control Option Command L 　Works even when the menu isn't open
Inactivity15 minutes by default — change it under Settings → Auto-lock
Screen lockFor example, pressing Win + LFor example, pressing Control + Command + Q
SleepFor example, closing your laptop lid
Wait until files finish copying or transferring before you lock. Locking mid-transfer may leave files incomplete.

If you see "Disk in use — still trying to lock…", an app still has a file open on the drive. Close that app, then click Try locking again.

Quit NOOKK

Click the lock icon → Quit NOOKK (or press ⌘ Q while the menu is open). Your NOOKK Drive locks when NOOKK quits, and it always starts locked the next time.

Manage

Add a keyManage → Add a key

You can add several keys to one NOOKK Drive. Any of them can unlock it.

  1. Click the lock icon → Manage → Add a key, and touch a key that's already added when asked
  2. Plug in and touch the new NOOKK Key (you may be asked to set a PIN)
  3. You're done when you see the confirmation. Your recovery phrase stays the same

Remove a keyManage → Remove a key

If a key is lost or no longer used:

  1. Click the lock icon → Manage → Remove a key
  2. Choose the key to remove from the list
  3. Confirm as prompted to finish
You can't remove your last key or your recovery phrase — this keeps you from being locked out.

Lost a key: unlock with your recovery phraseManage → Unlock with recovery phrase

Still have another added key? Just unlock with it, then remove the lost one. If you have no keys at all:

  1. While your NOOKK Drive is locked, click the lock icon → Manage → Unlock with recovery phrase
  2. Enter the 24 words in numbered order — or paste the whole phrase into the first box
  3. Click Unlock. If it's wrong, you won't be told which word, so check each word's spelling and order
After unlocking, add a new key right away, then remove the lost one.

Decoy driveMac only

This is an advanced feature of the Mac version. It isn't available on Windows yet.

Set a separate decoy password: if you're ever forced to unlock, entering it opens a decoy drive instead of your real NOOKK Drive. Available only if you chose to use a PIN when creating your NOOKK Drive.

  1. Click the lock icon → Manage → Create decoy drive
  2. Enter your decoy password twice (at least 4 characters, 8+ recommended, different from your key PIN), then click Save
  3. You're done when you see "Decoy drive ready". Add some believable files to it
To change the decoy password, just set it again. This clears the files in the decoy drive; your NOOKK Drive isn't affected.

Delete NOOKK DriveManage → Delete NOOKK Drive

Keep Files
Removes it from NOOKK only. The encrypted data stays and can be added back later.
Delete Files
After one more confirmation, click Delete Permanently. This can't be undone.

Add it back on a new or reset computerAdd existing NOOKK Drive

  1. Copy your original NOOKK Drive folder to the new computer (or check it's still in place)
  2. Install NOOKK, click the lock icon → Add existing NOOKK Drive, and choose that folder
  3. Unlock it with your original NOOKK Key or recovery phrase
Windows and Mac NOOKK Drives use different formats and can't be moved between systems. The same NOOKK Key can still be used for a separate NOOKK Drive on each computer.
