Handling file-system paths in Windows can have many subtleties, and it’s easy to forget how some of this very intricate system works under the covers.

Also not to be missed are blog posts about Windows’ handling of File URIs:

• File URIs in Windows
• The Bizarre and Unhappy Story of File URLs
• CreateURLMoniker considered harmful
