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.
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 helpers are 16-bit (for OS/2 1.x) or 32-bit (for OS/2 2.x and up), are executed in user-space and contain the code used for typical filesystem maintenance, and are called by CHKDSK and FORMAT utilities. This four-piece scheme allowed developers to dynamically add a new bootable filesystem, as the ext2 driver for OS/2 demonstrated.
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. [41]
ext was the first in the series of extended file systems. In 1993, it was superseded by both ext2 and Xiafs, which competed for a time, but ext2 won because of its long-term viability: ext2 remedied issues with ext, such as the immutability of inodes and fragmentation. [5]
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.

FAT32 implementations in other operating systems allow an unlimited number of files up to the number of available clusters (that is, up to 268,304,373 files on volumes without long filenames). [nb 4] Maximum number of files on volume C [clarification needed], to 4,294,967,285 (2 32 − 11, up from about 2 28 − 11 [nb 4] in standard FAT32).
