UFSConnect vs Google Drive: Can You Really Replace a Windows File Server? (2026)

Short answer: not without losing most of what makes a Windows file server useful to IT.

Google Drive is designed as Google Workspace cloud storage. The identity layer is Google accounts, the permission layer is Shared Drive roles, and the access layer is Drive for Desktop's streaming client. None of those are compatible with how a Windows environment authenticates users (Active Directory), authorises access to folders (NTFS inheritance), or surfaces content to applications (mapped drive letters and UNC paths).

Organisations that try to use Google Drive as a file server replacement end up rebuilding their entire content access architecture from scratch: new identity provisioning via Google Cloud Directory Sync, new permission model from the ground up, application path updates for anything that depended on drive letters, and retraining for users who now interact with files through a streaming client rather than a drive.

UFSConnect takes the opposite approach. The file server stays. Active Directory stays. NTFS permissions stay. Drive letters stay. What changes is that users can now reach it over HTTPS from anywhere. For Windows-centric organisations the comparison isn't close — Google Drive isn't structurally designed to replace a Windows file server.

Google Drive authenticates users via Google accounts. For organisations running Active Directory, the bridge is Google Cloud Directory Sync (GCDS), which provisions Google accounts based on AD users and groups.

This is a provisioning workaround, not real integration. GCDS is a one-way sync that pushes user and group membership from AD into Google's identity system. Password authentication either happens at Google with a separate password (doubling up the user's credentials) or via SAML SSO against an identity provider. Group policy doesn't apply to Google Drive. Windows-side audit tools don't see Google activity. Changes to AD permissions don't propagate to Shared Drive roles.

UFSConnect authenticates users directly against Active Directory with Kerberos or LDAP, plus Entra ID for hybrid environments. The AD groups and user accounts that control NTFS permissions on the file server are the same groups and user accounts that control UFSConnect access. There's no synchronisation layer, no separate identity system, no divergence between Windows and cloud access rules.

NTFS permissions on a Windows file server are inheritance-based. Grant a user read access on a folder, and they see the folder and every sub-folder underneath with read access. Deny access on a sensitive sub-folder, and it becomes invisible in the folder tree. Folder visibility tracks access — if you can't access it, you don't see it.

Google Shared Drives use a role-based model. Managers, Content Managers, Contributors, Commenters, and Viewers each have different capabilities across an entire Shared Drive. You cannot easily hide a specific folder from a specific user while granting broader access to the rest of the drive. Limited Access folders exist but Managers always see them in the folder tree even when content is hidden.

For most Windows-shop organisations, the Shared Drive model doesn't map cleanly to their existing NTFS-based access controls. Re-implementing the existing permission structure on top of Shared Drives typically requires restructuring how content is organised — a significant re-architecture project on top of the migration itself.

Two situations where Google Drive/Workspace is structurally the better choice:

Google Workspace-committed organisations. If Gmail is your email, Google Calendar is your scheduling, and Google Docs/Sheets/Slides are where documents actually get authored, then Drive is the native backend for that content. Real-time co-editing is mature, comments flow across apps, and the platform makes sense end to end.

Greenfield or born-in-cloud organisations. If there's no existing Windows file server, no Active Directory, and no legacy permission model to preserve, Google Workspace can be a clean starting point. The decision then is Google Workspace versus Microsoft 365 rather than cloud versus file server.

Outside those two situations, Google Drive adds significant complexity for organisations with an existing Windows environment. It's not that Google Drive is a poor product — it isn't — but it's architected around different assumptions to a Windows file server. Bridging those assumptions is a bigger project than most organisations want to undertake.

Choose Google Drive / Workspace when:

• The organisation runs Google Workspace as its primary productivity suite.
• There is no existing Windows file server or Active Directory to preserve.
• Real-time co-editing on Google Docs / Sheets / Slides is the primary content workflow.
• The Shared Drive permission model aligns with how you want to organise content.

Choose UFSConnect when:

• Your organisation runs Windows file servers and Active Directory.
• NTFS permissions are the existing authorisation model and you want to keep it.
• Line-of-business applications depend on drive-letter paths or UNC shares.
• File locking for non-Google file types matters (CAD, video editing, legal DMS).
• Data must remain on your infrastructure for compliance or sovereignty reasons.
