<Updated information - I was mistaken in one very important detail>
<Final update. When I allowed "full control" on my files, then the Ubuntu system could see the files.> So, I guess this closes the issue, I just need to find out what caused all of my recent files to change permissions...
I have a cifs volume mounted from a windows server on my Ubuntu system. On it I can see all the files stored there before Jan 1, 2020, coincidentally, these invisible files are also the files saved under my Windows credentials, the other files are under other credentials. This directory is mounted using another set of credentials (different user), but all files on the Windows system say that they are read/execute for "everybody".
On 2/2/2022, I could see all files on this mount on 2/7/2022, I can only see those files not saved by my windows login credentials. My smb credentials to mount this network directory has not changed. I have not rebooted any computer in this discussion in the last week. I have umounted and mounted the folume, there was no change.
What could have caused this change? I don't know whether to "blame" the windows server hosting that directory or my Ubuntu system. I realize that this a broad question, but I am stumped. I have checked rwx permissions and access on both the Ubuntu and Windows 10 side, and see no differences between the files that Ubuntu can see and the ones it can't see, other than the file owner.
Are there any other suggestions on where to look for a critical difference, on either platform?
