Question: In Nautilus, I would like to add columns displaying metadatas contained in files.

This is mostly useful with audio and pictures files:

* Audio : Artist, album, Track Title, Year ...(ID3 Tags)
* Photos : Date taken, Image resolution,

Columns would be editable in the standard 'View - Visible Columns' option in Nautilus

Answer: 
Follow this excellent how-to: [Adding metadata columns in Nautilus (Ubuntu)](https://web.archive.org/web/20101118031846/http://www.overclock.net:80/linux-unix/515783-how-adding-metadata-columns-nautilus-ubuntu.html). 

Here is a screenshot I took after following the how-to:

There may be a problem with nautilus-python and this extension (maybe just as of Ubuntu 13.04). If so, try one of these two solutions:

1.

```
sudo ln -sf /usr/lib/x86_64-linux-gnu/libpython2.7.so.1 /usr/lib/libpython2.7.so.1
sudo ldconfig

```

(From <https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1157246>)
