macos – The file lock remained open even after the file was closed, the co-edition disappeared to launch it in my company

The latest MAC 10.14.x and MAC 10.15.x operating systems have degraded their behavior with Word applications on network drives mapped via SMB. These network drives are shared drives on the Windows-2019 file server or can be on any Linux file server.

Problems:

A] When we map an n / w drive to MAC10.14.x and higher with SMB and open a .docx file and close it, the file lock is not released by the client even after closing / forced application on the client. This takes a toll on our n / w users who work on co-editing the file for various needs of my business. Extensive testing has revealed that this problem is not visible on MAC10.12 / 10.13.

We can reconfirm this problem by listing the files open on the n / w drive on the PowerShell command of Windows2019 file servers "Get-SmbOpenFile", we will continue to see the client file lock even after closing / forcing the file / customer application.

Has anyone heard / observed this problem?

Are there any publications / fixes on this behavior that Apple has introduced since MAC10.14? It’s really degrading MAC usability and corrupting n / w user data and making the lives of shared disk administrators difficult !!!!

I created a vv1 directory and inside it created 500 files. ls -lrt showed size vv1 as 12288 as follows:

12 in total

drwxr-xr-x 2 cms ccsrm 12288 January 28 12:15 p.m. vv1

After deleting 500 files, it showed the same size

12 in total

drwxr-xr-x 2 cms ccsrm 12288 January 28 12:17 vv1

Why??
