Question

My Windows 7 system path looks something like this:

Path=C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Windows\system32;....

I am trying to set a new user variable based on whether its defined or not already:

IF NOT DEFINED DEFAULTP (
  echo Setting DEFAULTP to backup the system PATH
  SETX DEFAULTP=%PATH%
)

When I try to do this, I get an error that looks like this:

\NVIDIA was unexpected at this time.

Can anyone guess why?

Answer 1

Try this:

IF NOT DEFINED DEFAULTP (
  echo Setting DEFAULTP to backup the system PATH
  SETX DEFAULTP "%PATH%"
)

Edit: Running setx /? gives these examples:

Examples:
  SETX MACHINE COMPAQ
  SETX MACHINE “COMPAQ COMPUTER” /M
  SETX MYPATH “%PATH%”
  SETX MYPATH ~PATH~
