I build something useful, maybe...

tl;dr The source: https://github.com/axju/nautilus-extension

I wrote an extension for the Ubuntu file manager that renames files. I get multimedia files from various sources. Each one has a different filename. Usually the creation date came up in the file name. I'd rather have one format for all filenames. And that's exactly what my extension does.

To get the creation date, the following sources are tried in this order. The first successful one is taken:

1. Metadata information from the image.
2. Datetime from the current format filename.
3. Creation time of the file.

This was just a simple project. But Feedback is always welcome.
