Are file comments possible?

All file types. Basically, on a Mac you can append a note to any file via the file comments. I often used these for adding descriptions of equipment setups on recordings, for example, but they have many applications. I don't think you can do this with Linux, I just thought I should ask while I was wondering. It takes two clicks and some typing; it's very easy.

The Mac system is not perfect, though; the comments can be lost if you have a bad system crash; they are stored in the file's icon, I believe, and if it gets corrupted, so does the comment.
