qBittorrent & operating system versions

similar like this , I'm finding an english version

Windows will automatically delete the last "."
the delete and rename will ignore the last “.”

Steps to reproduce

the secound step I rename the Agatha.Christies.Poirot.S01-S13. to Agatha.Christies.Poirot.S01-S13 and it appear two folder
the folder with last “.” cannot be operated

2022/01/25  18:44    <DIR>          ..
2022/01/25  17:56    <DIR>          Agatha.Christies.Poirot.S01-S13.

The more troublesome thing is that now it seems that the command cannot delete or rename this(work on win 10, but not 2016)

....
I delete it in Linux use smb

tried on win 10, it auto remove the last "." in explorer and qbittorrent showed I/O wrong
So the explorer in server 2016 and win 10 behave differently

Using RD (remove directory) in a command prompt will remove it but you need to specify the location correctly.

rd /s "\?\E:\Our Code World\Workspace\folder_invalid.."

I tried, not work in server 2016. it seems it behaviour like transition product in win 7 to win 10
hadn't test in win8 or 8.1
I think qb may avoid the “.” come the last in file or folder name, though the other system can fix it

Because this system is coming to the end of its life cycle.
