Summary of the issue you are facing:
I use the Canon app to sync files from my Canon DSLR to my Android phone. I have the folder on the Android phone monitored by the NextCloud app to sync it as a photo/media folder back to my NextCloud server.
The sync works fine. There are some errors during the sync I believe caused by file locks caused by the ongoing upload from the camera to the phone.
Once completed, I go to my Windows 11 laptop and it syncs the files down. Once the Windows 11 client has completed the sync it then starts to bring up Case Conflict errors for all the new images. The cause of the conflict appears to be “.jpg” vs “.JPG” in the filename. The originals all have lower case jpg.
For these I have just been adding a “zz” to the end of the filename then deleting them all once completed as they are effectively duplicates. I don’t recall the issue prior to the mobile app release that implemented the fix for missing upload files a couple of months ago, but that may be coincidental.
As a note, files uploaded from the separate media upload folder for the android camera app do not appear to cause this issue.
I have looked through the forum and GitHub and I cannot see anything recent relating to this so I was wondering if anyone had come across anything similar.
This is not an urgent issue as I have a simple workaround and other options if needs be.
Note, I have not down the path of digging through log files as yet.
Thankyou very much.
