You can define the batch file commands by typing them in the space provided, or you can use the Copy all and Replace all buttons to copy and paste from your computer’s clipboard. The following environment variables are available for use in the commands:
•%PATHTOFIXES%: Contains the full path to the current folder, with a trailing backslash.
•%LSFN%:The Language-Specific File Name variable provides a reference to the update file name and extension; the full path to the file is not included.
