There is a `FileSystemHost::FileSystemHandle()` method. Can you get access to the `FileSystemHost` object? But I think your point may be that it is not easy to get access to it...

Libfuse seems to issue this operation call when it gets a [`FUSE_COPY_FILE_RANGE`](https://github.com/libfuse/libfuse/blob/fuse-3.5.0/lib/fuse_lowlevel.c#L2425) opcode from the Linux kernel. I will have to better understand when the Linux kernel sends this opcode,...

@fsgeek thank you for your comments. Your expertise in these matters is invaluable. When I was first designing the WinFsp locking model, I struggled to understand the roles of MainResource...

I am fairly certain that Explorer has different rules for searching network drives rather than local drives. (Although I could not tell you exactly what heuristics it uses.) - Does...

@pfrejo you are welcome. And thank you for the workaround!

@i3v thanks for the report. I do not have a good answer for you regarding this problem. Here is some speculation based on work I did on a related project....

I will look into this, but from your description this is likely not a WinFsp problem. (Please note: the below is just speculation on my part.) For Explorer to notice...

> In the steps to reproduce, the files do not update for either the first or the second explorer Window. Interesting. This makes it more likely that there is indeed...

`GetSecurityByName` does double duty: it retrieves the security descriptor of the file/directory, but also returns the file attributes. If `GetSecurityByName` is not implemented, the WinFsp machinery has no way of...
