How do I Unignore a file in TortoiseSVN?

Question

I ignored a file in TortoiseSVN by mistake. How do I reverse this and add the file to my repository?

Answer 1

In my case there was another problem: the global ignore list in tortoise Settings, General.

Tortoise ships by default with .so files in the ignore list and we store these in source control (yes I know this is far from ideal). Removing them from the list sorted it out for me.
