The access path is the location Microsoft DOS or Windows looks when a command is not an internal command or in the current directory. For example, when typing in “fdisk” as a command, if the access path is not set to the location of fdisk.exe, you’ll receive a “bad command or file name” error message. Even if this file exists elsewhere on the computer.
