PCMan File Manager
PCMan File Manager (PCManFM) is a file manager application, developed by Hong Jen Yee from Taiwan, which is meant to be a replacement for GNOME Files, Dolphin and Thunar. PCManFM was the standard file manager in LXDE until it was discontinued, and it remains the standard file manager for LXQt. Since 2010, PCManFM has undergone a complete rewrite from scratch; build instructions, setup and configuration have changed in the process.
