Google Drive does not have a "deny" or "block" permission that explicitly prevents someone from viewing a file

Google Drive works with positive permissions only—you grant access to people, and everyone else has no access by default. There is no setting that says "deny this person" or "block this user." If someone has access, it is because you (or someone with sharing rights) gave it to them. If you want to remove someone's access, you stop sharing the file with them.

This design is simpler than systems that support both allow and deny rules, but it means you cannot selectively block one person while keeping a file shared with others in the same organization. You either share it or you do not.

Key Takeaways

  • Google Drive uses only positive permissions—you grant access to specific people, and no one else can see the file.
  • To remove someone's access, you must stop sharing the file with them; there is no "deny" setting.
  • If a file is shared with your entire organization or a group, you cannot block one individual person from seeing it.
  • Removing access takes effect when ready, and the person will no longer see the file in their Drive or in search results.
  • If you suspect someone accessed a file before you removed them, you can check the version history and activity log to see what they did.

How to remove someone's access to a file

Open the file in Google Drive, click the Share button in the top right, and look at the list of people who have access. Find the person you want to remove and click the trash icon next to their name. Confirm the removal. That person will lose access when ready.

If the file is shared with a group or your entire organization, removing one person is not possible through the sharing menu. You would need to stop sharing with the group or organization entirely, then re-share with individual people and exclude the one you want to block. This is time-consuming and impractical for large teams, which is why many organizations use folder-level permissions instead of file-level sharing.

What happens when you remove someone

The person you removed will no longer see the file in their Google Drive, in search results, or in shared-with-me sections. If they have a direct link to the file, clicking it will show an error saying they do not have access. They cannot undo this or regain access on their own.

Removing access does not delete any changes they made before removal. If they edited a document, their edits stay in the version history. You can see what they changed and when by opening the version history panel (in Docs, Sheets, or Slides, click File > Version history). If you need to undo their specific edits, you can restore an earlier version of the file.

Sharing with groups or your organization

If you share a file with a Google Group or your entire organization, you cannot block one person from that group. The file is either shared with the group or it is not. To exclude someone, you would need to remove the group-level share and instead share the file with individual people, leaving out the person you want to block.

Some organizations use Google Workspace admin controls to restrict access at a higher level—for example, an admin can prevent certain users from accessing Google Drive entirely, or limit sharing outside the organization. These are organization-wide policies, not file-level denials. If you work in a Workspace environment and need to block someone from a specific file, ask your IT administrator whether they have set up any policies that might help.

Difference between removing access and changing permissions

Removing someone is not the same as changing their permission level. If someone has Editor access, you can downgrade them to Viewer instead of removing them entirely. Click the permission level next to their name and select a lower level. They will still see the file but cannot make changes.

The three permission levels are: Viewer (read-only), Commenter (can add comments but not edit), and Editor (can make changes). Downgrading is useful if you want to keep someone in the loop but limit what they can do. Removing them is the only way to hide the file from them completely.

Checking who has accessed a file and what they changed

If you removed someone and want to know what they did while they had access, open the file and click the Activity button (in Docs, Sheets, or Slides, it is in the top right). The activity log shows who accessed the file, when, and what changes they made. You can see edits, comments, and downloads.

In Google Docs, Sheets, and Slides, you can also open Version history to see every saved version of the file and who made each change. Click on a version to see what it looked like at that point. If you need to undo someone's work, you can restore an earlier version, which will overwrite all changes made after that point.

Frequently Asked Questions

Can I block someone from a file if it is shared with my whole team?

No, not directly. If the file is shared with a group or your entire organization, you cannot exclude one person. You would need to stop sharing with the group and instead share with individual team members, leaving out the person you want to block. This is impractical for large teams, so most organizations use folder permissions instead.

What if someone has the link to a file I removed them from?

If they try to open the file using the link, they will see an error message saying they do not have access. The link itself does not work for them anymore. They cannot bypass this by using the link—access is tied to their account, not the link.

Does removing someone delete their comments or edits?

No. Their edits stay in the document, and their comments remain visible. Removing access only prevents them from seeing or changing the file going forward. If you need to remove their comments, you can delete them manually. If you need to undo their edits, restore an earlier version of the file.

Can I set up a rule to automatically block certain people from my files?

Google Drive does not have automatic blocking rules at the file level. If you work in Google Workspace, your administrator may have set up organization-wide policies that restrict sharing or access. Contact your IT department to learn what policies are in place.

If I remove someone and then re-share the file with them later, will they see the old version history?

Yes. Version history is part of the file itself, not tied to who has access. When you re-share the file with someone, they can see the entire version history, including changes made before they were removed and re-added.
