Failed to show folder picker

Failed to show folder picker.

ERROR_INVALID_PARAMETER: Параметр задан неверно. [::SHCreateItemFromParsingName(defaultFolderPath.c_str(), nullptr, IID_PPV_ARGS(defaultFolderItem.init()))]

What is the error? I work with webdav folder and get this when click "browse folder" button

The following version should give a better error message. What do you get?

I set this folder without problem in dialog window, then click Browse again and get error.

The path looks fine, the only unusual part that could explain ERROR_INVALID_PARAMETER are the Cyrillic characters. Maybe a limitation of the web server. In my tests accessing a wevdav share with these characters worked without error.

It works, but shows this error. What limitations are you talking about?

This means, this is not a problem that FFS can fix, most likely a bug in the web dav implementation. The best FFS can do is to show a warning and continue (instead of the error and abort as it was before). That's better than nothing, but it does not "work" in the sense that it does not pre-select the path in the folder picker as it should.
