I'm developing a pure Windows batch tool FileNameValidator that checks if supplied with batch arguments or typed by a user file paths & names are absolute & valid under current Windows version, before user code is run using these paths\names. The tool is different from snippets posted on this topic on SO, as it presents an automated user input validator for multiple path & file names entered either as batch arguments or typed manually. Other threads solutions are based on manual single path or name check by using regex. This tool checks path & file validity by test-writing a target folder to disk. So far the tool can check up to 9 local or network filepath & name arguments. "Local drives only" limitation was lifted.
I ask, how to a) check more than 9 arguments, b) lift user input requirements stated in code comments. None of these questions were addressed in a few SO threads on this topic. The tool is purely batch based, while other topics discuss C++ regex, or powershell related techniques, or limited batch regex supported by FINDSTR.

:: Checks if files name.ext or path entered as arguments or typed are absolute & valid in installed Windows version
:: by trying to create a new directory with a given path\name, if not exists already and target disk is accesible
:: If missing in batch arguments or invalid, user can type new or add to ":default" & choose default file names or paths
:: File variable names must use matching 3-letter ID with "save to" directory path variables (i.e. esd_dir\esd_file)
:: Default values, path & name variables, and arguments numbering must match ([arg1 & dir1 & pat1],[var.iso & file.iso])
