1. It's because when you try to delete a folder with the "del" command, it asks you to confirm if you want to delete files in the folder (hence the asterisk)
C:\>del ish
C:\ish\*, Are you sure (Y/N)? y
This will not remove the folder.
To remove the folder itself, use the "rmdir" command. Note that it will not delete folders that has files it in, so either do "rmdir /S foldername" or connect commands together like "del /Q ish && rmdir ish".
/Q means that it won't ask you for confirmation.
You can always issue the "help" command and see all available commands, then use "command /?" to get detailed help about the program.
2. You can only start programs that are written to run in CMD. Those that has a GUI will not run in CMD. Unless they are written to do both (which is rare, but nirsoft seems to do it
).
Start them up without "start" command.
