I'll often get a picture of a car that's been made gorgeous by other artists, using paths for every conceivable aspect of the of the look. I don't need 28 paths. I might need two, and those other paths get in the way. Same goes for alpha channels. And for the final pic, I may not want or need any channels or paths.

Paths and channels can useful for creating a picture but once the look has been achieved they are no longer needed and can get in the way when imported into other programs. So I'll save a file with all the working paths and channels, then a copy with nothing but the finished pic.

Hope that helps.

Why would you want to delete paths and/or alpha channels?  Wouldn't doing that ruin your picture?

Fantastic. Thanks, Evan. Great tip.

FWIW I use a script that deletes all channels and paths at once:

#target photoshop
app.bringToFront();
var theImage = app.activeDocument;
theImage.pathItems.removeAll();
theImage.channels.removeAll();

By the way, wouldn't it be nice if, in Photoshop, you could select all the paths or alpha channels at one time and drag them to the trash? I often receive files with dozens of paths and deleting them one at a time is a pain.
