The mklost+found command creates a lost+found directory in the current directory. mklost+found also creates (and then removes) a number of empty files so that there will be empty slots for fsck. The fsck command reconnects any orphaned files and directories by placing them in the lost+found directory with an assigned inode number. mklost+found is not normally needed since newfs automatically creates the lost+found directory when a new file system is created.
