What is TrekMail Drive? Built-in File Storage

TrekMail Drive is the file storage that comes built into your TrekMail account. You already have a place to send and receive email — Drive is the place to store the files that go with it. Logos and brand assets your team needs to attach to client mail. Invoices and contracts you want to keep alongside the conversations they belong to. Quote PDFs you want to send to a prospect through a download link instead of a 12 MB attachment that bounces.

Drive is built into every TrekMail plan, including Nano. You access it from the same dashboard you already use for domains and mailboxes.

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, click Drive in the sidebar, and you're looking at it. This is where your account owner — and any mailbox you've shared a folder with — sees account-wide files. Use it for assets that belong to the company, not to one person: brand assets, contracts, shared client folders, an "Onboarding" folder every mailbox needs to read.

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 that's bigger than 18 MB and TrekMail will quietly upload it to your Drive and replace the attachment with a download link. The recipient sees a normal-looking message, not a giant blob their inbox might 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 doesn't have to live only in a browser tab. You can connect it to the file managers and sync apps you already use — Finder on a Mac, File Explorer on Windows, rclone for nightly backups, Documents on your iPhone, DAVx⁵ on Android. Once connected, your Drive folders appear next to your local files. Drag a PDF in, double-click a contract to open it in Preview or Word, save the changes — it all flows 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 on its own without changing your main login. Pick the permissions each device gets (view-only for a phone, view+edit for your work laptop), give it a name like "Office MacBook" or "Backup script", and you're set.

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, and 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.

If your account fills the pool, you can either delete what you no longer need or buy more space with the Drive Add-on — a separate subscription that adds anywhere from 250 GB to 100 TB on top of your plan, billed monthly or yearly. The Add-on is independent of your mail plan: a Starter account can buy 50 TB, an Agency account can stay on the included pool. Resize up or down whenever you want.

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.

What agents can do with Drive

TrekMail Drive is also available through the REST API and MCP server for scoped automation. Agents can use Drive scopes to read folders, upload files, create public share links, run reviewed bulk operations, and check storage status. The MCP server includes 42 Drive tools (files, folders, share links, bulk operations, sync-device passwords, add-on status), and the full TrekMail MCP surface now has 209 tools.

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.
