External commands are the commands that are often created while installing a new application
and these commands mostly have no use except calling that application and support files. Means These commands are ships with Application and extend the use of our CMD. Due to Extension of working of command prompt from external application these are knows as External Commands. Few external commands can only be executed in the ‘Run’ dialog box (start → Run), but not on the command prompt, and those commands include ‘firefox’. The ‘firefox’ command can be executed only from the run line, that too if the firefox application is installed on that machine and it won’t work on the command prompt. Likewise the ‘firefox’ there are various other external commands such as the “PsTools” which includes commands like, PsExec, PsFile, PsGetSid, PsInfo, PsKill, PsList, PsLoggedOn and so on.
