What is TrekMail Drive? Built-in File Storage

TrekMail Drive is file storage built into your TrekMail account. Use it for files that go with your email, such as logos and brand assets, invoices and contracts, or quote PDFs. Instead of attaching a large file that a recipient's provider may reject, send it with a download link.

Drive is available when your account has Drive access through an active mail plan, Drive Add-on, or trial. You access it from the same dashboard you already use for domains and mailboxes. If Drive is not available in your account, see the Drive Add-on options in Billing before planning a file migration.

Two places you'll see Drive

Drive shows up in two parts of TrekMail, and they serve different jobs.

Account Drive is the dashboard storage. Open the dashboard and click Drive in the sidebar. The account owner manages it. Folders shared with the account appear to mailbox users inside webmail Drive, while private Account Drive folders remain visible only in the dashboard. Use it for assets that belong to the company, not to one person.

Webmail Drive is the per-mailbox storage. Each mailbox has its own private Drive space tucked into the webmail interface. Use it for files that belong to one person: their working documents, their personal scans, the receipt they need to forward to accounting next week. A mailbox owner can also see any folder the account owner has shared with the whole account, so the two views overlap.

The split mirrors how teams already work. Some files are "ours." Some files are "mine." TrekMail Drive doesn't force you to pick one model.

What Drive can do

The features you'd expect from a file manager are all here. The ones worth calling out:

• Color-labeled folders: pick a colour for any folder so your eye finds it fast in a long list. Useful for a "Hot clients" folder or a "Tax 2026" folder you want to spot at a glance.
• Folders shared across mailboxes: when the account owner shares a folder with the account, every mailbox in that account sees it inside their webmail Drive. Add a file to that folder once and your whole team has it.
• Public download links: generate a link to any file that anyone with the link can download. Optional expiry date. Optional download limit (1 to 100,000). Revoke any time from the same panel that created it.
• Large attachment auto-routing: attach a file in webmail above the attachment threshold and TrekMail can upload it to Drive and add a download link to the message. The recipient receives a link instead of a large attachment that their provider may reject.
• Trash and 30-day recovery: files and folders you delete go to trash first. They stay recoverable for 30 days unless you choose to empty trash sooner. Permanent delete is always a separate, deliberate click.
• Resilient uploads for large files: large files upload in chunks so a flaky connection doesn't lose your progress. Completed chunks are kept even if the upload is interrupted.
• Bulk operations: select 50 files with one click, move them all to a different folder in one action, restore 200 trashed items in one go. No "do it one at a time" tedium.

Sync to your desktop and phone

Drive does not have to live only in a browser tab. You can connect it to file managers and sync apps you already use, such as Finder on a Mac, File Explorer on Windows, rclone for backups, Documents on iPhone, and DAVx⁵ on Android. Once connected, your Drive folders appear next to your local files. Drag in a PDF, open a contract in Preview or Word, and save your changes. They sync back to TrekMail.

The connection uses device passwords, one per app or computer. You generate them on the Sync devices page in the dashboard, and each one can be revoked without changing your main login. Choose only the permissions the device needs, give it a recognizable name such as "Office MacBook" or "Backup script", then keep the one-time password in the app's password field.

For a short tour of how this works and which app is right for you, see Drive Sync overview. Each platform has its own step-by-step:

• Connect from macOS Finder
• Connect from Windows Explorer
• Connect with Cyberduck, recommended on either OS for big uploads
• Connect with rclone, the command-line option for backups and scripts
• Connect on Android with DAVx⁵
• Connect on iPhone with Documents

If a connection misbehaves, Drive Sync troubleshooting covers the common fixes.

Storage and the Drive Add-on

Every TrekMail plan comes with storage. When the account has Drive access, that storage is pooled across email, mailbox files, and account files. Your inbox, your colleague's mailbox Drive, and the shared "Brand assets" folder all draw from the same pool. Nano accounts need a Drive add-on or trial before they can store Drive files.

If your account fills the pool, delete what you no longer need or add capacity with the Drive Add-on. It is a separate subscription from the mail plan. Check the current size and billing choices in the dashboard before purchasing or resizing it.

There's a separate guide on Pooled Storage Quotas Explained that walks through exactly how the pool is calculated, what counts against it, and what happens when you hit the limit.

Turning Drive off for someone

Within an account that has Drive access, Drive is on for every mailbox by default and storage is pooled, so one person storing personal files spends the same allowance everyone else needs for mail. If that does not suit how you run the account, each mailbox has a Limits tab where Drive can be reduced to email attachments only, or switched off entirely. Email keeps working in both cases.

See Limiting or Turning Off Drive for a Mailbox.

What agents can do with Drive

TrekMail Drive is also available through the REST API and MCP server for scoped automation. The complete local stdio catalog currently has 261 tools, including 42 Drive tools; each connection receives only the tools allowed by its scopes, plan, toolsets, transport, and safety gates. Agents can read folders, upload files, create public share links, run reviewed bulk operations, and check storage status.

Drive Add-on billing remains user-controlled: purchase, resize, and cancel actions are handled in the dashboard, not through API or MCP write tools. For API and AI-agent integration, see Drive API Overview and Drive MCP Tools Overview.
