I have scripted SetPath.bat which accomplishes the following tasks:

1. Adds the specified folder to your path, if it is not already present.

2. Creates the folder, if it is missing.

NOTE: The new PATH will NOT be active until the computer is restarted. 

NOTE: You can use workstation.bat to run SetPath.bat on all the workstations in your domain.

Usage:

SetPath NewFolder

where NewFolder is the fully qualified new folder path.

Examples:

SetPath "C:\Program Files\My Stuff"

SetPath D:\utility

NOTE: If the NewFolder string already exists, it will not be added. If D:\utilityManager already exists in the PATH, then D:\utility will NOT be appended.

NOTE: The NewFolder tree can NOT be more than 8 branches deep.

SetPath.bat uses Reg.exe from the Windows 2000 Support Tools.

SetPath.bat contains:
