Hidden unix dot files not show with WebDav clients (e.g, davx5, davfs2), but appears in Web browser

[jt0in3e]

I've set up nginx to serve WebDav with modules ngx_http_dav_module and nginx-dav-ext-module, as well as enabled indexing of folders with this module, using directives fancyindex on; and fancyindex_show_dotfiles on;.

Hidden files (in the case dot files in linux, e.g. '.hidden') are shown in a webbrowser, but not available in Webdav clients/mounts.

What can be wrong here?

found the issue #41 of 'nginx-dav-ext-module', saying 'PROPFIND now don't return hidden files'.
I suppose the problem is hidden there
