Abort Batch Script if File does not exist

Whether a file is existing can easily be checked with "IF EXIST <FileName>". If you want to check whether a file is not existing, you can just use "IF NOT EXIST" instead. The command "EXIT" cancels the script execution.

So, in your case you can just add the following line for each required file:

IF NOT EXIST important-file.dat EXIT

If the file "important-file.dat" is not existing, the command after the check will be executed and the whole script terminates. If the file is existing, the next line will be processed.
