Does gallery-dl have built-in tools for auto rename downloaded files?

[zajimumaaa]

I have downloaded files with certain custom filename format and also save the metadata in json file. Now I changed my mind about the filename format and wanted to change it. Is it possible to auto rename the downloaded files without downloading all of them again?

There sort of is something like this now, I think..

By using the rename post-processor
https://gdl-org.github.io/docs/configuration.html#postprocessor-configuration

Might depend on your specific plan. Without any example it's a bit hard to tell.

This post-processor can be used from CLI with

  --rename FORMAT             Rename previously downloaded files from FORMAT
                              to the current filename format
  --rename-to FORMAT          Rename previously downloaded files from the
                              current filename format to FORMAT
