Select the card root. Not DATALOG, not a single month folder — the whole card.
A ResMed card (AirSense and AirCurve 10/11, S9) carries:
DATALOG/ — the nightly detail, one folder per date, holding the high-rate waveform
and event files. This is the bulk of the card and the part that takes time to import.
SETTINGS/ — your therapy settings as the machine recorded them over time.
STR.edf — the summary file: one row per night, covering usage, leak, AHI and
pressure statistics. This is what makes a long history import quickly even when the
detailed nights are pruned off the card.
Identification.* — what the machine says it is. This is how the importer knows
the model.
Practical notes
The card prunes itself. Machines keep a limited window of detailed nights but a much
longer summary history. If your charts show a year of trends but only a few months of
detailed waveforms, that is the card, not the import.
Upload the whole card each time. Re-uploading is safe — de-duplication skips
everything already present, and the new nights merge in.
Don't reorganise the card. Moving files out of DATALOG breaks the date structure
the importer reads.
Cards over 5 GB go up in batches; the batches merge automatically.
Oximetry, where you record it on a compatible setup, arrives with the nightly data
and appears on its own tiles rather than in the flow charts.
If a card refuses to be recognised, send it through the DropBox fallback rather than
reformatting anything — that is the route that gets a layout looked at.
Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.
