A USB drive has been purchased to move files between Windows, *nix, and Macintosh servers. Which of the following filesystems is the BEST choice to ensure the drive can read and be written to by all…

ext2 is primarily used by Linux and Unix-like systems and has limited native read/write support on Windows and macOS without additional drivers.

FAT32 is widely compatible across Windows, Linux (a common *nix variant), and macOS systems, making it the most suitable filesystem for universal read and write access on a USB drive used to transfer files between these diverse operating environments. While it has limitations (e.g., 4GB max file size), its ubiquitous support makes it the best common denominator.

NTFS is the native filesystem for Windows and offers limited native read-only support on macOS (read-write usually requires third-party tools) and read-only support on many Linux distributions (read-write is often available but sometimes less robust than native filesystems).

UFS (Unix File System) is primarily used in Unix and Unix-like operating systems (like FreeBSD, Solaris) and has very limited to no native support on Windows or macOS.
