What it means
A UFDR is the report package an extraction tool writes. Reading it is not the problem; reading it beside the body-camera video, the 911 audio, the cloud return and the custody record is. A separate viewer shows one phone; an investigation has more than one source.
What to look for
The questions to ask: Is the file read bit for bit, with the original untouched? Does every row say how well it was read (full, partial or raw), or does the viewer hide what it could not parse? Can the phone's timeline merge with everything else in the case?
How DEVI does it
In DEVI, a UFDR, a raw extraction or another tool's output is booked as an item, hashed, and read into the case timeline and map with every row marked full, partial or raw. The file-types page lists exactly what is read in full.
