Largest files

MB: This is a simple mega-widget to display largest files than a given limit. It is based on snit, on the fileutil package and on the hrfilesize package, which can be found one the file size page. The icons are given by the excellent icons package. The user can customize :

  • the directory in which the search in done,
  • the file size limit,
  • the file size unit (B, KB, MB, etc...),
  • the file size limiter : min/max.

It should be able to handle large files over than 2 GB, but I did not check that. I use it to make some space on my hard drives.
