File Name Generator

The name of a file can contain several parts, which describe the content of the file with meta data. You can enter your meta data in the following fields, check if you like to have it in your file name and rearrange the parts for the order of the output.

This can be the date of creation, editing or publication of the file.
This can be an institution or a working group inside an organization.
This can be the person who wrote the document or edited it most recently.
This can be structural information, e.g. if the file is a note, poster or flyer.
This is the official title of the document or a short form or abrevation.
This can be a (numeric) state or version (e.g. release, submission).
  • Date
  • Organization
  • Author
  • Category
  • Title
  • Version
Each field will be joined in the generated name with the choosen character.


Maybe two fields should not be joined with a character (e.g. "authorYY_title"). The position of the join exception can be selected.

  • no "Umlaut" marks or similar signs, transforming to a substitute (e.g. ä -> ae, ß -> ss, é -> e)
  • underscores instead of spaces
  • maximum length (with pathname) of 256 characters
  • standard formats (e.g. timestamp with YYYYMMDD)
