@beecksche said in QFileSystemModel doesn't support the network paths and external drives?: I think the easiest way is to write your own file system model. Or, presumably extend QFileSystemModel by subclassing it. @jeanmilost I just don't think you can access network, as per https://stackoverflow.com/a/33856139/489865 and @beecksche's comment above.

The solution to that problem is to insert the following call to the constructor of the file processing class: QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8")); Concerning the shell: I use BusyBox (its light) which doesn't provide locale and the environment variables like LANG=en_US.UTF-8. For compiling BusyBox configurations can or have to be given containing CONFIG_LAST_SUPPORTED_WCHAR=0 the number is the last displayable number of the Unicode list, 0 signifies that all characters shall be displayed, it was set to 767 which includes west European characters. The excluded characters are replaced by the character defined in the same configs, in my case it is "?".

Then, AFAUI, you have all what you need to continue. If implementing the proxy model looks daunting start by just a custom QAbstractItemModel with a QListView and once you have what you want you can go with the proxy and the shifting I suggested before.

Using QFile::handle

I am very sorry that my words arise felling of my impatience. I really do not mean this.
