You can use the following steps to prevent Trident from consuming additional disk space.

• Disable offline mail

• Turn off automatic downloading of chat media

• Sign out of all accounts and sign back in

• Clean the ~/.Trident-Direct folder

Disabling Offline Mail 

When Offline Mail is enabled, Trident downloads and stores mailbox data locally. This may lead to increased disk space usage for accounts with large mailboxes, such as those containing emails dating back several years or emails with large file attachments.

New or recently created mailboxes with limited historical data typically have a minimal impact on local storage.

Tip: To reduce both cloud and local storage usage, users who frequently share large files can consider using WorkDrive or other cloud storage solutions instead of email attachments.

To disable offline Mail for email accounts that have a large inbox footprint:

1. Right-click the Mail account for which you want to disable offline Mail from the folder pane.

2. Select Disable Offline from the menu list.

3. Select Disable in the alert dialog box that appears.

Alternatively, you can also:

1. Click your profile image in the top-right corner of the app.

2. Select Settings from the menu list.

3. Select Accounts.

4. Hover over the Mail account for which you want to disable offline Mail and click the More Options icon that appears.

5. Select Disable Offline from the menu list.

You can also click open the Mail account and toggle off the Enable Offline Sync option under the Sync Mail section. Toggle the option on to enable offline sync.

Disabling Auto-Downloading Media in Chat 

1. Click your profile image in the top-right corner of the app.
   

2. Select Settings from the menu list.

3. In the General page, toggle the Auto-download media in chat option off.
   

Signing Out of All Accounts 

If disk usage increases again after cleanup, this may indicate:

• A large or persistent local cache

• Offline mail is still enabled for one or more accounts

• A synchronization issue

You can further reset local data by signing out of all accounts. To do so:

1. Open Trident.

2. Go to the main menu and click Trident.

3. Select Sign Out of All Accounts from the menu list.

4. Select Sign Out in the alert that opens.

Cleaning the ~/.Trident-Direct folder       

To keep the app fast and responsive, we store contact photos, media, and documents on your device as you view them. This avoids re-downloading the same content repeatedly, reduces loading time, and helps the app work smoothly even with slow or unstable internet connections.

Over time, the ~/.Trident-Direct folder can grow significantly (sometimes exceeding 10–20 GB) due to accumulated cache files or locally stored email data.

To clear unnecessary files in the ~/.Trident-Direct folder:

1. Go to Menu Bar > Trident > Quit Trident or use the cmd + Q shortcut to quit Trident completely and ensure that it isn't running in the background.

2. Open Finder.

3. Navigate to your home directory.

4. Press Command + Shift + . (period) to show hidden files.

5. Locate the ~/.Trident-Direct folder.

6. Inside the folder, look for a subfolder named Cache, then select Move to Trash to delete it.

Note: If the issue persists after performing the above steps, contact customer support at trident@zohosupport.com for further assistance.
