In the list of XP File Types, if I select 'File Folder':
Q1: Why is Edit and Remove greyed out?
You don't edit a directory. You add files to it, move files into or
out of it, delete files from it. You edit a spreadsheet, or a word
doc, or a text file, something like that.
I'm not sure what "Remove" means. But, in general, the options in the
list are actions that can be taken on a file: open, edit, execute. You
don't do those things with a directory.
Q2: Where do these entries come from? (Most/all don't seem to work
anyway.)
From the registry. They are tied to the file type, and that's
determined from the file's extension. There's a registry entry in each
user's registry for each file type. It lists the possible actions to
be taken on the file, and what program and options should be used for
each one.
