In addition, substitution of FOR variable references has been enhanced. You can now use the following optional syntax:      %%~I         - expands %%I removing any surrounding quotes (")     %%~fI        - expands %%I to a fully qualified path name     %%~dI        - expands %%I to a drive letter only     %%~pI        - expands %%I to a path only     %%~nI        - expands %%I to a file name only     %%~xI        - expands %%I to a file extension only     %%~sI        - expanded path contains short names only     %%~aI        - expands %%I to file attributes of file     %%~tI        - expands %%I to date/time of file     %%~zI        - expands %%I to size of file     %%~$PATH:I   - searches the directories listed in the PATH                    environment variable and expands %%I to the                    fully qualified name of the first one found.                    If the environment variable name is not                    defined or the file is not found by the                    search, then this modifier expands to the                    empty string  The modifiers can be combined to get compound results:      %%~dpI       - expands %%I to a drive letter and path only     %%~nxI       - expands %%I to a file name and extension only     %%~fsI       - expands %%I to a full path name with short names only     %%~dp$PATH:I - searches the directories listed in the PATH                    environment variable for %%I and expands to the                    drive letter and path of the first one found.     %%~ftzaI     - expands %%I to a DIR like output line  In the above examples %%I and PATH can be replaced by other valid values.  The %%~ syntax is terminated by a valid FOR variable name. Picking upper case variable names like %%I makes it more readable and avoids confusion with the modifiers, which are not case sensitive.
