QFile::remove() strange refresh problem in windows desktop

[squidge]

TBH, since you can register file/dir notifications with the shell, I kinda expected the shell to use that itself so that when someone modifies a folder, regardless of where it is, it refreshes the open windows that are showing that directory.

Every app can see special directories like "Desktop", but I don't think any of the applications I have treat it any differently than any other dir.

You mean you can register your app to receive file notifications from the shell, right? The context of "someone" is very important. If "someone" is the typical user, then they used the shell to make the modifications so the shell already knows about it. If "someone" is a program written with the standard library for file IO, then the shell will know when it is asked to check. If "someone" is a program written against the shell api, then the shell will know just as if the user himself had done it.

but I don't think any of the applications I have treat it any differently than any other dir.

It comes down to whether or not it is suitable for the shell to wait until it is asked by the user (or another process) to refresh the desktop. Also it is worth mentioning that for most purposes the shell api is overkill for file operations.
