Is there a tool that can scan an FTP directory and build a visual representation of disk usage? I'm running on Windows so that platform is my preference for this tool, but a *NIX tool would also be useful. I'm thinking along the lines of WinDirStat, KDirStat and TreeSize. At first I thought WinDirStat might be able to scan an FTP directory, but it was not so. FOSS is a plus, but not a requirement (I'm not against paying for good software).
I'd like to also have a simple report on how many of what types of files are present, largest files, etc. Much like the simple file type reporting in *DirStat.
