SMF – Search my Files v15

   is the fastest duplicate files finder and a multi-dimensional
    file searcher,
    file copier / mover,
    file deleter / eraser,
    and duplicate previewer…

It has excessive search filter capabilities and a SQLite driven result reporting tool, with which you can sub-filter the results according to your needs.

With this combination the search possibilities are nearly unlimited.

  • Search for files by last modified date / keyword / file attribute
  • Search for pictures of a certain filesize / dimension / EXIF info
  • Search for MP3 by length / author / bitrate
  • Search for duplicate pictures of a certain filesize / dimension
  • etc., etc.

Furthermore SMF enables you to open / copy / move / delete / erase any file found.

Initiated searches can be performed in the background while minimizing SMF to the tray.
