Shared File Access Review Checklist: How to Audit Permissions and Remove Stale Links

Overview

Secure file sharing is not only about choosing a reputable storage or collaboration platform. It also depends on reviewing who can access each file, how they can use it, and whether that access is still needed. A link created for a short project can remain active long after the project ends. A former contractor may still appear as a guest. A folder shared with “anyone with the link” may contain documents that were intended for one client.

A file sharing permissions audit is a structured review of those access paths. The goal is not to remove access indiscriminately. It is to match each person, group, link, and permission level to a current business need. Before changing anything, identify the files and folders in scope, note active projects, and confirm who owns the content. If a document is part of a contract or signing process, preserve the approved version and audit information before changing its location or permissions. The guidance in this contract organization guide can help with naming, versions, and retention decisions.

Use the following review table as a simple starting point:

Checklist by scenario

Shared folders and team workspaces

• List the folders that contain contracts, personal information, financial records, credentials, or internal work.
• Review direct users, groups, guests, and inherited permissions for each folder.
• Confirm that editors genuinely need to modify files. Change unnecessary editors to viewers or commenters if the platform supports those roles.
• Check whether a broad parent-folder permission gives access to more content than intended.
• Identify folders with no clear owner and assign a responsible person or team.
• Remove access for people who have left the project, changed roles, or no longer work with the organization.

Public and organization-wide links

• Search for links available to anyone with the URL, anyone on the internet, or everyone in the organization.
• Ask why each link exists, who received it, and whether the original purpose is still valid.
• Replace open links with named-recipient access when the audience is known.
• Set an expiration date when the platform allows it and the sharing purpose is temporary.
• Disable download, copy, or printing options when recipients only need to review content and the platform provides those controls.
• After revoking a link, verify that an old URL no longer opens the file or folder.

Client and external collaborator access

• Match every guest account to a current client, vendor, project, or other documented relationship.
• Confirm that the external person is accessing only the intended folder or file, not an entire workspace.
• Check whether the client needs an editable source file or only a final PDF.
• Use a separate client-facing folder when internal notes, drafts, or unrelated projects are stored nearby.
• Record the expected end date and the person responsible for closing access.
• For sensitive documents, use a controlled sharing workflow rather than attaching multiple uncontrolled copies to email. See the client file-sharing workflow for a practical sequence.

Employee offboarding or project completion

• Remove the person from shared folders, groups, guest lists, and active links.
• Transfer ownership of important files and confirm that automated workflows do not depend on the departing account.
• Revoke links created specifically for the completed project.
• Archive the final approved files according to the organization’s retention process.
• Check copied or duplicated folders, since removing access from one location may not affect another copy.

What to double-check

Permission labels are not always equivalent across platforms, so read the actual effect of each setting rather than relying on a familiar name. “Viewer,” for example, may still allow downloading, while “editor” may allow resharing. Confirm the details in the platform’s permission panel and test with a non-owner account when the file is sensitive.

Review these areas before completing the audit:

• Inherited access: A file may appear restricted while its parent folder remains broadly shared.
• Group membership: Removing one individual does not remove access provided through a team, department, or project group.
• Link settings: Check whether a link is public, organization-only, restricted to named recipients, or protected by another control.
• Expiration behavior: Confirm whether expiration ends access, requires renewal, or applies only to a particular recipient.
• Resharing: Determine whether recipients can invite others or create new links.
• Copies and exports: Revoking access to the original does not necessarily remove downloaded files, screenshots, forwarded attachments, or local copies.
• Audit records: Save the review date, reviewer, affected item, decision, and follow-up owner.

When sharing a PDF with a client, also check whether the document contains hidden comments, tracked changes, metadata, or unnecessary personal information. A password can add a useful layer for some workflows, but it should not replace careful recipient and permission choices. Review how to password protect a PDF before sending it online when that control fits the situation.

Revocation record template

Keep a short record for each meaningful change:

• Date and reviewer: When the decision was made and who made it.
• File or folder: The exact name and location.
• Access removed or changed: Person, group, or link; previous and new permission.
• Reason: Project ended, role changed, duplicate link, incorrect audience, or another clear explanation.
• Owner and follow-up: Who will verify the change and when.

Common mistakes

• Auditing only the top-level folders: Nested folders and individual files may have separate sharing rules.
• Deleting a person instead of understanding the access path: The user may still retain access through a group or public link.
• Leaving links active for convenience: A reusable link is easy to share beyond its original audience. Prefer named access for confidential material.
• Removing access without preserving work: Before revoking permissions, confirm that active collaborators have the approved files, necessary exports, and a new location if needed.
• Assuming view-only means no copying: Check download, print, copy, and reshare controls separately.
• Failing to notify affected collaborators: A short message explaining a permission change can prevent confusion and duplicate access requests.
• Recording no evidence of the review: Without a simple log, it is difficult to distinguish deliberate access from an overlooked setting later.

When to revisit

Run a shared file access review at least before seasonal planning cycles and whenever workflows or tools change. A quarterly schedule is a practical baseline for active teams, but the right interval depends on the sensitivity and turnover of the files. Review immediately after employee or contractor offboarding, a client engagement ending, a major project handoff, a workspace migration, or a suspected incorrect share.

Revisit this checklist whenever your storage platform changes its permission labels, link controls, guest settings, group behavior, or administrator tools. Product interfaces and available controls can change, so verify the current settings rather than relying on an old screenshot or remembered workflow.

To finish each review, choose a small sample of restricted files and test them from the perspective of a viewer, an external guest, and a person with no access. Confirm that revoked links fail, current collaborators can still do their work, and the access log is complete. Then schedule the next review and assign an owner. Consistent, documented checks make it easier to share files securely without creating unnecessary disruption.
