Why a dropped connection can't break your upload

Uploading a big folder used to mean babysitting a progress bar and praying your wifi held. In Total Vault it doesn't. If your connection drops, you close the tab, or your laptop reloads mid-upload, your upload picks up right where it left off — nothing that already made it gets sent again.

Every file goes up in chunks rather than as one all-or-nothing transfer. A 4 GB video, for example, is split into many pieces that upload in parallel. As each piece lands, Total Vault records it — right there in your browser — so it has a running map of what's done and what's left.

That map lives on your own device, so it survives a refresh or a tab close. When you reopen Total Vault, it reads the map, asks our servers which pieces already arrived, and uploads only the ones still missing. A file that was 90% done resumes at 90%, not 0%.

• Chunked transfer — each file is uploaded as many small pieces, straight to storage.
• Progress saved locally — finished pieces are remembered on your device as you go.
• Resume from where you stopped — only the missing pieces get re-sent, never the whole file.
• Double-checked on arrival — once a file fully lands, we double-check it actually opens, so you know it's safe.

If an upload gets cut off — wifi drop, sleep, a reload — the upload panel in the bottom-right corner shows it as an interrupted upload the next time you open Total Vault. Here's how to finish it:

• Look for the upload panel in the bottom-right corner. If anything was interrupted, it reads something like 2 interrupted uploads.
• Press Resume all to send everything that didn't finish. Total Vault re-sends only the missing pieces.
• To handle them one at a time, single-click the panel to open the full-screen view, then press Resume on an individual file.
• Changed your mind about one? Discard it and it won't come back.

Want to stop an upload that's running right now? Press the X on the upload panel. Total Vault asks you to confirm, and reminds you that anything already uploaded stays saved — canceling never throws away pieces that already made it.

There's no separate Pause button — but you don't really need one. Because progress is saved continuously, simply closing the tab or stopping has the same effect: when you return, the upload is waiting to resume.

Getting the bytes uploaded is only half the job. Once a file fully lands, Total Vault double-checks it on our side — independently of your browser — to confirm the file actually works and isn't corrupt. That's the step that earns the green check. Until then a file shows as uploaded; once it's confirmed, it's safe.

And because that double-check runs on our servers, you can close the tab the moment your files land. The confirmation keeps going without you.
