The short version: take the SD card out of the machine, select the whole card folder, and let the app do the rest in the background. 1. Make sure the right profile is active. Data always imports into the active profile — its name shows at the top right. A profile holds one person's therapy data; a fresh account starts with two included. 2. Put the card in your computer. Card reader or adapter, either way. Do not rename or move anything on the card, and do not tidy it up first — the folder layout is how the importer recognises your machine. 3. Open the upload dialog and pick the card root. In the New Look interface that is the Upload CPAP data icon in the right rail; in Legacy it is the upload section on the welcome page. The dialog tells you how many files and how much data it found. 4. Upload. Large folders go up in chunks of roughly 95 MB with per-chunk progress. Leave the tab open until the last chunk lands — navigating away discards the upload, and the browser will warn you first. Once the upload finishes you can go anywhere; the import runs on the server. 5. Let the import run. You get a fifteen-second Cancel window right after the last chunk, and a Cancel button for the whole import after that. A few months of data import in minutes; a multi-year card can take tens of minutes. You can log out and it keeps going, and you get an email when it finishes. Things that trip people up One upload at a time per browser. A second tab is blocked on purpose. 5 GB per upload. Bigger cards go up in batches — they merge automatically. "Everything was a duplicate" is de-duplication working, not a failure. Unrecognised folder? The app offers the DropBox fallback instead of importing garbage. Use it — that is how unsupported layouts get looked at. Vendor-specific card layouts have their own topics in Importing Data. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

A related one, because it produces the same "is it stuck?" feeling: an import that shows "Queued (position N)". Two imports run at a time across the whole service. If both slots are busy — which happens when somebody uploads to several profiles back to back — yours waits, and starts by itself when a slot frees. Nothing is lost by queueing and nothing needs re-uploading. The processing indicator stays visible the whole time; that is how you know it is alive. The genuinely stuck case looks different: the indicator disappears and no sessions arrive. The server's watchdog marks a dead import as failed and tells you to re-upload — and because of de-duplication, re-uploading is safe.

Worth saying out loud for anybody new reading this: you cannot break your data by uploading too often. People new to this tend to upload once, get a scare, and then not touch it for a month. Upload the whole card whenever you happen to have it out — after a trip, at the end of a month, whenever. Only the new nights land. There is no counter, no penalty, and no way to create a duplicate night by trying.

One hardware footnote, because it costs people an evening. You need a card reader that actually reads the card, and on most machines the card is a full-size SD card sitting behind a flap. Take it out with the machine switched off, and put it back the same way. Removing the card does not erase anything and does not harm the machine — the machine writes to it again the next night. Do not rename, tidy, move or "clean up" anything on the card before uploading. The folder names are the importer's map. If you have already tidied a card, no harm done — put the files back where they were, or upload the card again after the next night's recording.
