Backing up my current configuration of PDFE

[puckman]

Hi Rui
Thanks for helping me out earlier this month. Restoring my PDF library and my preferred PDFE configuration is still undergoing growing pains.  Moving forward, I am resolved to not only back up my PDF files but the configuration of PDFE as well.
 
Can you verify or comment on my backup strategy below?
1. I have my PDF files that I am working on incrementally on a seperate scratch disk that I will back up incrementally as I change their properties.
2. I found two PDFE folders on my system which I assume contains the configuration files etc. One folder is in  C:\Program Files (x86); another is in C:\Users\[myprofile]\AppData\Roaming.
3. I found a questionalable folder elsewhere on my system drive C:\Users\[myprofile]\AppData\Local\Microsoft\Windows\CloudStore\{94b5dd38-99e0-43c7-bdd5-1c548f3503ff}\windows.data.apps.appmetadata\appmetadatalist\pdf explorer_is1.

You only need to use the settings backup/restore functionality under the preferences tool. No need to manually backup any folder.

That "questionalable folder" is related to Windows functionality. Google Search AI says it is a registry path segment used inside the Windows Registry's CloudStore hive (under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore). Windows uses this database to cache application display names, publisher info, icon details, and last-launch timestamps for installed programs.
