Find filenames by any word as fast as possible using index files with the free sfk iname command.

sfk name[2] word [word2] [!exclude] [.ext]

find filenames as fast as possible by using
index files created by sfk index or gindex.

sfk name word [word2] [word3] [...]
  will use local index files zz-index.txt
     - in the current folder
     - in the parent folder
     - and so on, until the root folder "\"
  and also the global Base Index file from
  and then lists all file names from those indexes
  having the given words in their name or path.
  Under windows, instead of C:\zz-index.txt
  it will read C:\zz-index\zz-index.txt

sfk name2 word [word2] [word3] [...]
  does the same as name, but also includes
  the global Extended Index file.

sfk gname uses only the global index.
sfk lname uses only local index files.
