Template-based renaming utility

Project description

Tempren - template-based file renaming utility

run-tests codecov Maintainability PyPI version status

tempren is a powerful file renaming utility that uses flexible template expressions to create new file paths and names. New file paths can be based on original filename, created independently or from the underlying file's tags. Rich library of built-in tag extraction modules helps with tagging many common file types.


  • Template-based filename/path generation
  • Audio/Video/Images/etc metadata extraction
  • Configurable, metadata-based file selection (filtering)
  • Metadata-based sorting


Currently only PyPI installation is supported, just run following command:

$ pip install [--user] tempren


Manual gives a tour of all tempren features and (until quickstart is created) should work as a guide.


Note: When experimenting on your own please use --dry-run flag!
Tempren will not override your files by default but invalid template can mangle their names.
