PCManFM-Qt is the Qt port of PCManFM, the file manager of LXDE.

In LXQt sessions it is in addition used to handle the desktop. Nevertheless it can be used independently of LXQt as well.

PCManFM-Qt is licensed under the terms of the GPLv2 or any later version. See file LICENSE for its full text.


Compiling source code

Runtime dependencies are qtx11extras, lxmenu-data, liblxqt and libfm-qt. Additional build dependencies is CMake.

Code configuration is handled by CMake. CMake variable CMAKE_INSTALL_PREFIX has to be set to /usr on most operating systems, depending on the way library paths are dealt with on 64bit systems variables like CMAKE_INSTALL_LIBDIR may have to be set as well.

To build run make, to install make install which accepts variable DESTDIR as usual.

Binary packages

Official binary packages are available in Arch Linux, Debian, Fedora and openSUSE (Leap and Tumbleweed) and most other distributions.


The file manager functionality should be self-explanatory, handling of the desktop deserves some notes:

To handle the desktop binary pcmanfm-qt has to be launched with switch --desktop set. Optionally switch --profile can be used to safe settings specific to certain session types like the different desktop environments.
In LXQt sessions, PCManFM-Qt is launched with theses switches set as LXQt Module.

To configure the desktop there's a dialogue "Desktop Preferences". Technically it corresponds with launching pcmanfm-qt with switch --desktop-pref set. It is available in the desktop's context menu and included as topic "Desktop" in sub-menu Preferences - LXQt settings of the panel's main menu as well as the Configuration Center of lxqt-config.

All switches (command line options) mentioned above are explained in detail in man 1 pcmanfm-qt.
