The script below creates a child process to perform FileExist() separately from the main script so that it avoids halting the script when an unknown network path is passed.
However, the command, Process close, does not close the given process despite its ErrorLevel indicates it succeeded to close. Task Manager shows the child process still exists.
FileExistTimeout() ; this checks if the necessary parameters are passed
; this checks if the given path exists by creating a child process with the given timeout
