I have version 126.96.36.19936 which I think is the current version.
Using the overwrite option I still have all detailed graphs etc for the last 47 days. This includes data from two different machines, and three different SD cards.
I'm new to this stuff so dumb question... why would you not just choose discard?
that's what I do. The old data doesn't change, so it only downloads the newest data and leaves the old data untouched on both the card and the computer.
I am able to click on previous dates and see the data all the way back to the day I started therapy.
Maybe there was another bug related to using the discard function as well?
I am new to CPAP and this software. However, at first glance it appears you can generate a detailed report for each day you download. This creates a pdf file which can be retrieved at any time. I think (but you guys will need to confirm) that by doing this it won't matter if you overwrite or discard - your data is always viewable in that saved report or am I missing something.
Remember that pulling up the report to look at on the screen does not save it. You have to explicitly save the report if you want to keep it around.
So if you generate the daily report AND use "Save as.." to save it to a location outside of the folder where your ResScan data is stored, then you should always be able to access the saved daily reports using a pdf reader such as Acrobat no matter what ResScan does with the data files in its own folder.
Of course the one thing you can do within ResScan which you cannot do with a saved report pdf file is dynamically drill down into the data. That said, the saved report file has a lot of information in a very nice format to archive daily details. I hadn't really looked at ResScan reports before you brought it up.
This ResScan discard vs. overwrite issue seems to only apply to certain versions of the program and perhaps only to certain machines as well, but I am not aware of which program versions nor which machines are the ones at risk.
The safe option to choose when downloading each day's new data is "Discard" which means do not mess with existing daily data files and only add the new data coming off the SD card.
I have not tested the other option and don't have any desire to speak from experience regarding deleted data. Plenty of other people have already spoken with authority on this.
Agreed. To be safe always download with discard option and "save as" for reports. Thanks for the feedback.
