How do I install .icns?

[tzus]

I have a folder of .icns files and when viewed in Preview they are in .tiff format. How do I install them? I have changed icons before using the superb My Icons app but it just does not want to know these. I have even tried saving them as .png and then trying them.

Any ideas?

After further searching I found the answer here:

If you already have the .icns files, go to Versiontracker and find "Icns2Rsrc"

Open the .icns file, in Icns2Rsrc.app, and save it as a .Rsrc file. Now the copy/paste method will work, as it will have the icon in the top right, and not an "icns" icon.

The Program, Icns2Rsrc.app comes in a ".sit" file. If you cannot open it, Search Versiontracker for a program called "stuffit expander"
