File in use issue

We have recently noticed when connecting via WebDav using NetDrive, it doesn’t prompt us that a file is in use.
In version 3 of NetDrive we have tried ticking the always check file on server, doesn’t do anything.
Have back dated to version 2.6.2 and it does the same thing.
Is there a setting that can be changed so it always warns/advises that the file is open/in use by someone else?

@steve-4ff6 In next version of NetDrive (3.8) files will be open as readonly when other user already opens the file. But it works only for MS office files. We have plan to implement general file lock/unlock feature which works on all file types. Thanks for your feedback.
