Remove an Atlas?

[Gaudon]

I cannot remove an atlas from a Unity build.

I've tried restarting Unity, but it's still listed.

Used Assets, sorted by uncompressed size:
 21.3 mb    15.5% Assets/Textures/Atlas/titleScreenAtlas.png
10.7 mb    7.7% Assets/Textures/Atlas/SinglePlayerAtlas.png

This atlas doesn't exist, nor does this file exist. It did at one point, and now I can't remove It.

What's going on here?

If it doesn't exist, then where is it coming from? This isn't an NGUI question by the way. This is entirely Unity.

Indeed, I suspect unity has some form of "intelligent" asset caching system. I also posted over there and haven't gotten a response.

Although I am certain the file doesn't exist and is no longer referenced in the project. All Textures converted to sprites now use a new Atlas map that holds everything.
