Highlights: Added long path (upto 32,000 characters) support. Abstracted file system so adding new types of file systems like database or zip file will be easier. Improved path security, prevented leaking underlying physical paths in error messages for all cases. Improved quota handling so exceeding the limit in subfolders is prevented. For FileVista, language setting is separated into two: display language controls the user interface language and format language controls the number and date/time formats.
