In computing, convert is a command-line utility included in the Windows NT operating system line. It is used to convert volumes using the FAT file systems to NTFS . [ 1 ]
This means that when files are copied or moved between NTFS and FAT partitions, the OS needs to convert timestamps on the fly. But if some files are moved when daylight saving time (DST) is in effect, and other files are moved when standard time is in effect, there can be some ambiguities in the conversions. As a result, especially shortly ...
A basic data partition can be formatted with any file system, although most commonly BDPs are formatted with the NTFS, exFAT, or FAT32 file systems. To programmatically determine which file system a BDP contains, Microsoft specifies that one should inspect the BIOS Parameter Block that is contained in the BDP's Volume Boot Record .
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.

Microsoft Windows additionally comes with a pre-installed tool to convert a FAT file system into NTFS directly without the need to rewrite all files, though this cannot be reversed easily. [10] The FAT file system is used in removable media such as floppy disks , super-floppies , memory and flash memory cards or USB flash drives .
VFAT, a variant of FAT with an extended directory format, was introduced in Windows 95 and Windows NT 3.5. It allowed mixed-case Unicode long filenames (LFNs) in addition to classic 8.3 names by using multiple 32-byte directory entry records for long filenames (in such a way that old 8.3 system software will only recognize one as the valid directory entry).

Explorer was subsequently enhanced to support adding and deleting files in a FAT-formatted image, and later with EXT2, EXT3 and NTFS file systems. Until 2007, GHOST Explorer could not edit NTFS images. GHOST Explorer could work with images from older versions but only slowly; version 4 images contain indexes to find files rapidly.
