PCManFM

PCManFM is a free file manager application and the standard file manager of LXDE.

Installation

Install the pcmanfm package.

Additional features

Add lxmenu-data to be offered a list of "Installed applications" when opening a file.

Add shared_mime_info to recognise different file types.

USB Automounting

For USB mounting support, install gvfs and add the following line to your configuration:[1]

  environment.variables.GIO_EXTRA_MODULES = [ "${pkgs.gvfs}/lib/gio/modules" ];

If automounting still does not work you may need to explicitly enable devmon and udisks2. Keep in mind that all removable media will automatically mounted even without pcmanfm running.

configuration.nix

    services.udisks2.enable = true;
    services.devmon.enable = true;
