Parse env:Path with PowerShell

The environment variable PATH (combined SYSTEM PATH and USER PATH) can be tricky to parse if you want to check for each folder it contains.  This is due to the support of various formatting styles.  For example, this is a valid PATH statement:

  • Folder with spaces
  • Folder without spaces
  • Folder with an ending backslash ( \ )
  • Folder without an ending backslash ( \ )
  • Folder with a semicolon ( ; )  in the middle
  • Folder with a semicolon ( ; ) at the end
  • Blank folder ( ;; )

To prove it out:

Happy coding!
