Converts file allocation table (FAT) and FAT32 volumes to the NTFS file system, leaving existing files and directories intact at startup after Autochk runs. Volumes converted to the NTFS file system cannot be converted back to FAT or FAT32.
You cannot run Autoconv on the command-line. This will only be run at startup, if set through Convert.exe.
