This article is from the MachTen & CodeBuilder FAQ, by Jaime Julca email@example.com with numerous contributions by others.
Tenon maps the UNIX file system to the MacOS file system. So, with MachTen
and MacOS, there is a single consistent file system. This means that
everything is accessible to both MachTen and MacOS. You can 'see' the UNIX
directories and files on the Finder desktop and you can 'see' the Macintosh
folders and files from a UNIX terminal window using 'cd' and 'ls'.
E2. Does MachTen have a native file system?
MachTen uses the Macintosh file system (HFS) and adds a Network File System
(NFS). MachTen 4.1 will ship with a native UNIX fast file system.
E3. Does CodeBuilder have a native file system?
CodeBuilder includes two support file trees: one is a Macintosh file system
(HFS) and the other is a native fast file system (FFS). The developer can
use either one, the tradeoff is performance vs. Mac Finder integration.
