Here you can find some useful application to look for big files on disk for Windows and Linux. These disk tools are all free software, and very useful to find big files on disk and free disk space.

On Windows: WinDirStat

• Download and install WinDirStat
• Run WinDirStat on your disks (it will take time)
• You’ll see a coloured map of file occupation by file type

On Linux command line: ncdu

• On Ubuntu / Debian
  • apt-get install ncdu
  • cd /dir/to/check
  • ncdu

• On CentOS / Fedora / RedHat
  • yum install ncdu
  • cd /dir/to/check
  • ncdu

Press c to show the number of files / directories contained inside each directory, and C to sort them for number of items, pressing ? will show all available shortcuts.

On Linux with window manager (recent OS)

On a GNOME system (e.g. Ubuntu 20), the Disk Usage Analyzer is already installed, you can run with the command “baobab”. If not installed, you can:

apt-get install baobab

On Linux with window manager (legacy OS)

• CentOS / Fedora / RedHat
  • yum install k4dirstat
• On Ubuntu / Debian
  • apt-get install k4dirstat

Again, you’ll see a coloured map of file occupation by file type.
