Where are RESMED files located on a PC?

[moondoggy]

I’m wondering if anyone can point me in the right direction?  I’m migrating from an old Windows 10 PC to a Windows 11 PC.  I had a copy of Resmed 6.0 and tried to install it but had problems.  Although I knew my ID and password from my old PC and my username is the same on both machines, the software could not validate my credentials so I uninstalled that version and installed 5.9 as what was suggested on the forum. 
 
The weird thing is that I can still logon on my old PC and see my history, but I cannot for the life of me determine where Resmed is picking this data up (i.e. folder and filenames).  After looking at my old data I determined that my S9 only kept 12 months of data and there’s a rather large gap between the old history and what’s on the card so I started over on my new PC with what I have.  Even after reentering my profile and patient history and downloading my data off the card and saving everything, I still cannot figure out where Resmed is storing the history.  Can anyone help?

Crimson Nape is correct that the location mentioned is the standard location, but it does not have to be if you want to place the files somewhere else. In my case, the OSCAR files are saved to my "D" drive in my "OSCAR Data" folder. This makes it simple to find and more importantly to backup. I have external hard drives (2) for local redundant backup and also send the OSCAR files to the "cloud" for even more security. I have had as many as 5 ResMed Machines so having an easy to find file location is helpful. Also, I have had computer crashes, virus infections, and moving to new PCs over the years (I currently have two W10 PCs both with identical OSCAR programs/files). For more fun, I also use SleepHQ, but in that program's system it is 100% Internet based with no need for local backup (but, I use both OSCAR & SleepHQ anyway). Both have their advantages, I know how to use both, so why not?

Overkill to say the least, but I am a retired engineer and "backups" where always on my mind since I worked mainly with public safety customers and believe me they demand backups to the extreme.
