The short answer: You can't password-protect a folder in Google Drive. What Drive offers is access control: set the folder's General access to Restricted so only people you add can open it, and remove people any time. Google Workspace client-side encryption goes further, but it's only on Enterprise Plus, Frontline Plus and Education Standard and Plus, and an admin has to set up an external key service first. On any account you can upload an encrypted archive instead, at the cost of extracting files to edit them. ZapLock encrypts the Drive folder itself: the folder keeps its name and place, Drive only ever holds encrypted files, and you open it with your ZapQR sign-in on Mac, Windows or Android.
Three ways people try, and where they stop
Restricted sharing
In Share, set General access to Restricted so only people you add can open the folder. Remove them any time.
- No password, and nothing extra is encrypted
- Anyone signed in to your Google account sees everything
- Anyone with the link opens it without signing in
Workspace client-side encryption
Files are encrypted in the browser with keys your organization controls, so Google can't read them.
- Enterprise Plus, Frontline Plus, Education Standard and Plus
- An admin sets up a key service and identity provider first
- Not on personal Google accounts
Upload an encrypted archive
Zip the folder with a password (7-Zip with AES-256, or a Mac encrypted disk image) and upload the file.
- Download and extract to edit, then upload again
- Forget the password and it won't open
- Everyone you share with needs the same password
Deleting the plain copies takes two steps. Drive keeps deleted files in the Trash for 30 days, and its version history can keep older versions of a file for up to 30 days or 100 newer versions, or longer if someone chose Keep forever. After you lock a folder, empty the Trash and check version history on anything sensitive.

How to lock a Google Drive folder with ZapLock
On a Mac or Windows PC with Google Drive for desktop, or on an Android phone with the Google Drive app. iPhone and iPad can't lock Google Drive folders today: iOS doesn't let other apps open Google Drive folders from Files.
Install ZapLock and sign in
Get it from the Mac App Store, Microsoft Store or Google Play, and sign in with a free ZapQR account.
Sign in on a second device
Sign in on another phone or computer too. Each device holds its own share of a folder's key, so losing one doesn't lock you out.
Get the folder ready
Download any Google Docs, Sheets or Slides in it as Office files. On a computer, stay online while it locks; if Google Drive for desktop streams your files, make the folder available offline first so every file is on the disk.
Lock the folder
On a Mac, right-click the folder in the Google Drive location in Finder and choose Services → Protect with ZapLock. On Windows, right-click it in File Explorer and choose Protect with ZapQR. On Android, choose Add folder… and pick it under Google Drive: ZapLock downloads the files, encrypts them, uploads the locked versions and deletes the plain originals.
Empty the Drive Trash
The plain originals go to Drive's Trash, which keeps them for 30 days. Empty it to finish, and check version history on anything sensitive.
What ZapLock won't do
Worth knowing up front, so nothing surprises you later.
- You need a free ZapQR account. That sign-in is what replaces the password.
- Opening a folder needs a connection to our service, which releases its half of the key. A new unlock waits until you're back online.
- If a folder's key lives on only one device and you lose that device, the folder can't be opened. Sign in on a second device before you lock anything you can't lose.
- No Linux, and the apps aren't open source.
- Sync services keep version history. If plain copies were ever synced, your provider may still hold them.
Google Drive folder lock FAQ
Can you password-protect a folder in Google Drive?
No. Google Drive has no password option for folders or files. You can restrict who it's shared with, and Google Workspace client-side encryption is available on a few business editions. To lock the folder itself on any Google account, encrypt its files before they reach Drive, with an encrypted archive or with ZapLock.
Does setting a folder to Restricted lock it?
It limits who Google lets open it: only people you've added, signed in to their Google accounts. It doesn't encrypt anything, so anyone who signs in to your account, or to the account of someone you shared with, sees the files. Switching General access to Anyone with the link opens the folder to anyone who has the link, without signing in.
Can Google see the files in my Drive?
Drive encrypts files on Google's servers, but with keys Google manages. Only Workspace client-side encryption, or encrypting files yourself before upload, keeps the key away from Google. ZapLock encrypts on your device with AES-256-GCM, so Drive only stores encrypted files.
Will a locked folder still sync with Google Drive?
Yes. The folder keeps its name and place in My Drive, and Google Drive keeps syncing it between your devices, but only encrypted files go up. The file names inside are encrypted too, so drive.google.com shows unreadable names.
What happens to the original, unencrypted files?
ZapLock replaces them with encrypted versions, and the plain originals end up in Drive's Trash, which keeps them for 30 days. Empty the Trash to remove them. Version history can also keep older versions of a file for up to 30 days or 100 newer versions, longer if someone chose Keep forever.
Can I lock a Google Drive folder from my iPhone?
Not today. iOS doesn't let other apps open Google Drive folders from the Files app, so ZapLock can't reach them there. Lock the folder from a Mac, a Windows PC or an Android phone. ZapLock on iPhone does lock folders in iCloud Drive and On My iPhone; see locking folders on iPhone.
Is there a free way to lock a Google Drive folder?
Yes. ZapLock's Free plan locks one folder for good, and opening folders is always free. A password-protected 7-Zip archive is free too, if you don't mind extracting files to edit them. Personal is $49 a year on the web for unlimited folders. See pricing.
Lock your first folder in a minute.
Free for one folder, for good. On Mac, Windows, iPhone, iPad and Android.
