Set up synchronization

When you set up synchronization between a cloud and a local folder, Tresorit continuously monitors both locations to ensure their contents remain identical.

• The sync feature is available only in the desktop apps – you cannot enable it in Tresorit Drive, Web Access, or on mobile devices.
• Tresorit protects your cloud content using end-to-end encryption. This means that files synced to your computer will be decrypted and no longer protected with any encryption.
• Sync requires an active internet connection. If you make changes to local versions while offline, they will be updated in the cloud once you're back online and Tresorit is running.

ℹ️ Sync is available for all Tresorit users. However, business subscription admins can apply policies to disable sync for team members.

Standard synchronization (full)

Standard sync is the primary sync method in Tresorit. When enabled, it synchronizes the entire contents of a folder between your device and the cloud.

Set up standard sync

You can set up sync from either the desktop app or your computer.

ℹ️ Sync Tresorit with NAS or a network drive.

Selective synchronization

The selective sync option allows you to exclude specific subfolders or files from syncing, so only the selected content will be updated both locally and in Tresorit.

ℹ️ The folder structure leading to the selected subfolders will also be saved to the local destination, because it's required for the synchronization path.

Set up selective sync

1. Open the Tresorit desktop app.
2. Right-click a folder.
3. Select    Selective sync.
4. Choose the local sync location, then click Next.
5. Check the subfolders you want to sync.
6. Confirm with Sync these items.
7. Wait until the content appears on your device (an orange checkmark    will appear on the cloud folder).

Sync only one subfolder

1. Right-click the subfolder in Tresorit.
2. Select    Sync this folder.
3. Browse the sync location.
4. Confirm with Sync.

Folder icons explained

Tresorit uses folder icons in the desktop app to indicate sync status.

• Only main folders display sync symbols; individual subfolders and files do not.
• These icons are not displayed on local folders.
• In Tresorit Drive, synced folders display a shortcut arrow that points to their sync location, allowing you to distinguish between synced and non-synced items at a glance.

Cloud icon	The folder exists only in the cloud and is accessible only via Tresorit.
Green checkmark	The folder is fully synced – all content is mirrored locally and in the cloud.
Orange checkmark	The folder is selectively synced – only selected parts are locally available.
Network drive icon	The folder is synced to a network drive, NAS, or external storage.
