Thanks for the reply, but I am a little confused by it. Let me try to be a little more clear on my part. I'm currently running Android Marshmallow 6.0.1, stock from my provider.
Folder A = Source folder on my PC
Folder B = On my phone's microSD card. I wish Folder B to mirror all changes, if any, from Folder A.
With that said, shouldn't Folder A be set to RO and Folder B set to RW?
In my initial post, I only set up Folder A in my PC's Resilio Sync application. From there, I used my phone to scan the QR code (either Folder A's RO or RW code) to initiate synchronization between the two devices. In my phone's Sync app, I directed Folder A to transfer/update its contents to Folder B. I also turned off selective sync.
With the RO QR code, I believe new files/subdirectories in Folder A not present in Folder B were added to Folder B. However, conflicting files (Folder A files on Folder B with newer timestamps) were not updated. With the RW QR code, conflicting files were resolved by files with newer timestamps overwritting older counterparts. However, subdirectories/files there were deleted from Folder A prior to sychronization were not deleted from Folder B and such conflicts were shown in Folder A after synchronization.
For example, in Folder A:
├───Alternative and Rock
│ ├───Built to Spill
│ │ ├───Album 1
│ │ └───Album 2
will look like this after synchronization (from Folder A, artist directory renamed and Album 3 subdirectory deleted):
├───Alternative and Rock
│ ├───Built to Spill
│ │ ├───Album 1
│ │ └───Album 2
│ ├───Conflicted.Built TO Spill
│ │ ├───Album 1
│ │ ├───Album 2
│ │ └───Album 3
From your quote, are you suggesting that I setup both Folder A (on my PC) and Folder B (on my phone) and point them to their respective directories for proper bidirectional syncing? For example, on my PC, Folder A (RO) receives a link from my phone's Folder B; on my phone, Folder B (RW) receives the QR code from my PC's Folder A. Will this establish that Folder B cannot update Folder A but any new or conflicting files from Folder A will be updated accordingly in Folder B? Will this prevent the creation of "Conflicted.X" in Folder A?
FYI: directory tree is 5525 lines long.
