When I make a recording on the HB, the first folder I see is "Record", inside this folder (example) is "R00001" and "R00001.dat. I do not to need to go any further to play HumViewer. At this point I load Humviewer, <File>, <open>, <Look in:>
Since I keep my recordings on my desktop then under "Look in" I scroll up to the "Desktop" file <SI Recordings>, file <record>, inside this file is R00001 and R00001.dat, highlight the dat file then <open> the program should start loading and play. At the top right side <play> to start playing the recording.
Now the files in the R00001 is: B000.IDX, B000.SON, B001.IDX, B001.SON, B002.IDX, B002.SON, B003.IDX, and B003.SON
Comparing your files to mine they are correct. The key is to load HumViewer then open the files until you can highlight the dat file and key open.
These are the same files in the R0000?, regardless of the record numbers.
Hope this makes sense.
