In OS/2 version 1.2 and later, the High Performance File System was designed with extended attributes in mind, but support for them was also retro-fitted on the FAT filesystem of DOS. For compatibility with other operating systems using a FAT partition, OS/2 attributes are stored inside a single file "EA DATA. SF" located in the root directory ...
The FAT file system was moved out of the Kernel to an IFS and was heavily optimized for performance, taking advantage of the 32-bit processing capabilities (being called FASTFAT). Original Windows NT 3.1 incorporated FAT, HPFS (Pinball) and the newly created NTFS drivers, along with a new and improved CD-ROM filesystem driver that incorporated ...
ext2 was the default filesystem in several Linux distributions, including Debian and Red Hat Linux, until supplanted by ext3, which is almost completely compatible with ext2 and is a journaling file system. ext2 is still the filesystem of choice for flash-based storage media (such as SD cards and USB flash drives) [citation needed] because its ...
convert is an external command first introduced with Windows 2000. [2] If the drive cannot be locked (for example, the drive is the system volume or the current drive) the command gives the option to convert the drive the next time the computer is restarted.
On Windows, FAT and FAT32 file systems can be converted to NTFS via the convert.exe utility, but not the reverse. [39] On Linux, ext2 can be converted to ext3 (and converted back), and ext3 can be converted to ext4 (but not back), [40] and both ext3 and ext4 can be converted to btrfs, and converted back until the undo information is deleted.

Although ext is not a specific file system name, it has been succeeded by ext2, ext3, and ext4. It has metadata structure inspired by traditional Unix filesystem principles, and was designed by Rémy Card to overcome certain limitations of the MINIX file system.
For example, the ext2 driver for OS/2 is simply a wrapper from the Linux's VFS to the OS/2's IFS and the Linux's ext2 kernel-based, and the HFS driver for OS/2 is a port of the hfsutils to the OS/2's IFS. There also exists a project that uses a Windows NT IFS driver for making NTFS work under Linux.
