File manager and desktop icon manager (Qt port of PCManFM and libfm) (source files)
PCMan File Manager (PCManFM) is a file manager application developed by Hong Jen Yee from Taiwan which is meant to be a replacement for Nautilus, Konqueror and Thunar. Released under the GNU General Public License, PCManFM is free software. PCManFM is the standard file manager in LXDE, which is also developed by the same author in conjunction with other developers. Since 2010, PCManFM has undergone a complete rewrite from scratch. So the new PCManFM is totally different from the old 0.5.x series.
