Why are there directories called local, locallow, and roaming under \users\\appdata? Ask question asked 16 years, 5 months ago modified 5 years, 5 months ago Trying to make space on my c drive.

Is it safe to delete it? If not, can it be 'pruned' without affecting installed applications? The original user's profile directory lives in a directory like c:\users\username\appdata. How can i refer to the current user's profile directory when using the windows command line?
